This question asks us to find the relationship between two pairs of words based on an analogy. We are given the first pair: ‘Liver’ is related to ‘Human Body’.

First, let's understand the relationship between ‘Liver’ and ‘Human Body’. The liver is a vital organ that is a part of the human body. It performs crucial functions within the body. So, the relationship is 'a functional part of' or 'contained within a larger system'.

Understanding the Analogy: Liver and Human Body

The analogy sets up a relationship where one item (Liver) is a key component or part of another item (Human Body). The liver is essential for the proper functioning of the human body.

Applying the Relationship to Motor

Now we need to find which option has a similar relationship with ‘Motor’. A motor is a device that converts electrical energy into mechanical energy, causing movement or driving a mechanism. It is often a functional part of a larger machine or device.

Let's examine the options:

• Option 1: Coil
  A coil is a component *within* a motor. It's a part of the motor itself, not something that contains or uses the motor as its main driving force. This relationship is different from a liver being part of a human body.
• Option 2: Metal
  Metal is a material that motors are made from. This describes the composition of the motor, not something that the motor is a functional part of or contained within. This does not match the liver-human body relationship.
• Option 3: Fan
  A fan is a device that uses a motor to operate. The motor rotates the blades of the fan, allowing it to move air. The motor is a crucial functional part of a fan, just like a liver is a crucial functional part of a human body. This fits the analogy.
• Option 4: Wings
  Wings are parts of various things like birds, insects, or airplanes. While some things with wings (like airplanes) use motors (engines), the wings themselves are not things that typically 'contain' or are directly powered *by* a single motor in the same way a fan is. The relationship is not as direct or universal as motor to fan.

Comparing the relationships, the most appropriate analogy is that a Motor is a functional component of a Fan, just as a Liver is a functional organ of a Human Body.

Conclusion for the Motor Analogy

Based on the analysis of the relationship between ‘Liver’ and ‘Human Body’ (functional part of a larger system), the word that shares a similar relationship with ‘Motor’ is ‘Fan’ because a motor is a key functional part that drives a fan.

Additional Information: Functional Components

In many systems and devices, different parts work together to achieve a specific function. Identifying these functional components is key to understanding how the system operates. For example:

• A heart is a functional component of the circulatory system in a human body.
• An engine is a functional component of a car, providing power.
• A processor is a functional component of a computer, performing calculations.

In this analogy, the motor is the functional component that enables the fan to perform its task of moving air.
