Option 1 suggests that both Assertion (A) and Reason (R) are true statements and that R properly explains A.

Option 2 also implies that both A and R are true but claims that R doesn`t serve as the correct explanation for A.

Option 3 is the right answer. This means that Assertion (A) is a true statement that Emperor Akbar marched towards Afghanistan with a huge army in 1581. However, Reason (R) is a false statement. Akbar was not on his way to reclaim Ferghana in Central Asia. Akbar`s ancestors hailed from Ferghana, however, there`s no evidence to suggest that he intended to reclaim this territory.

Option 4 suggests that A is false and R is true, this would imply that Akbar didn`t march towards Afghanistan but he was heading to reclaim his ancestral land. But this is incorrect as we know that Emperor Akbar did march towards Afghanistan, but not with the aim of reclaiming Ferghana.
