Solution Analysis

This question asks to evaluate two statements, Assertion (A) and Reason (R), regarding complex thematic maps and determine their truthfulness and the relationship between them.

Assertion (A) Analysis

Assertion (A) states: "Maps that are usually referring various attributes' information are called complex Thematic maps."

• Thematic maps display specific themes or data related to geographic areas.
• Complexity in thematic maps often arises from the need to represent multiple variables, detailed data, or intricate relationships between different attributes.
• Therefore, maps dealing with "various attributes' information" align with the definition of complex thematic maps.

Conclusion: Assertion (A) is true.

Reason (R) Analysis

Reason (R) states: "Complex Thematic Maps are used to show locations of earth's different features and activities."

• Thematic maps, by their nature, are designed to show spatial distributions.
• They commonly represent the locations of various geographical features (like mountains, rivers) and human activities (like population density, land use).
• This description accurately reflects a primary function of thematic maps, including complex ones.

Conclusion: Reason (R) is true.

Relationship between Assertion (A) and Reason (R)

We need to determine if Reason (R) correctly explains Assertion (A).

• Assertion (A) defines complex thematic maps based on their handling of "various attributes' information".
• Reason (R) describes the general purpose of these maps – showing "locations of earth's different features and activities".
• While Reason (R) is a true statement about thematic maps, it describes their general application rather than explaining *why* they are considered "complex". The complexity stems from the nature and diversity of the attributes being mapped, not just the act of showing locations.
• Thus, Reason (R) is true but does not provide the specific reason for the complexity mentioned in Assertion (A).

Final Answer Selection

Since both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation for Assertion (A), the correct option is the one that states this.

This matches Option 2: Both (A) and (R) are true, but (R) is not the correct explanation of (A).
