Which of the following Social Science questions promote acquisition of metacognitive knowledge ?

Correct option is B

The answer is (b).
The question "Find out the distance from your Mandal headquarters to District headquarters with the use of a map" promotes acquisition of metacognitive knowledge because it requires the student to think about their own thinking processes. They must first understand that a map is a representation of reality, and that the distance between two points on a map is not the same as the actual distance between those points on the ground. They must then use a scale to convert the map distance to the actual distance. This process of thinking about their own thinking is essential for metacognition.
The other answer choices do not promote metacognition as much because they are more focused on specific facts or skills. For example, answer choice (a) asks the student to explain why symbols are used on maps, which is a factual question. Answer choice (c) asks the student to explain why the actual distance on the ground is reduced on a map, which is a skill-based question. Answer choice (d) asks the student to list the important features of a map, which is a memory-based question.
