This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
Nylon

Odd One Out Reasoning

The question asks to identify the material that differs from the others in the list: Cotton, Nylon, Silk, and Cashmere. To find the odd one out, we need to classify these materials based on their origin.

Material Classification

  • Cotton: A natural fiber derived from plants.
  • Silk: A natural fiber produced by silkworms.
  • Cashmere: A natural fiber obtained from the hair of cashmere goats.
  • Nylon: A synthetic fiber manufactured by humans.

Identifying the Odd Material

Based on the classification:

  • Cotton, Silk, and Cashmere are all natural fibers.
  • Nylon is a synthetic fiber.

Since Nylon is man-made and the other three are natural, Nylon is the odd one out.
