*Q:13 Correct Answer* ✅ *(4) A is false but R is true* > *Explanation:* In pteridophytes (e.g., ferns), the sporophyte is the dominant and long-lived phase of the life cycle, not the gametophyte. However, pteridophytes do exhibit alternation of generations, where both the sporophyte and gametophyte are independent, although the gametophyte is small and short-lived. So, Assertion is false but the Reason is true.
