You are to examine these two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so, whether the reason is a correct explanation of the Assertion. Select your answer to these items using the codes given below. Assertion (A) : Bajadas or Piedmont alluvial plain extend for several miles away from a mountain front. Reason (A) : A series of adjacent alluvial fans sometimes coelesce to form an extensive piedmont alluvial plain which is also called Bajadas.

  1. Both A and R are true and R is the correct explanation of A.

  2. Both A and R are correct but R is not the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true.

A Correct answer
Explanation

Both A and R are true and R correctly explains A. The assertion that bajadas extend for miles from mountain fronts is true. The reason that adjacent alluvial fans coalesce (merge) to form extensive piedmont plains called bajadas is the correct geological explanation - this is exactly how bajadas form. Reason R directly explains why assertion A is true.
