Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Plant families like Convolvulaceae and Solanaceae are included in the order Polymoniales. Reason (R): The assignment of these plant families to an order is based mainly on vegetative characters. In the light of the above statements, choose the most appropriate answer from the options given below:
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A)
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A)
- C(A) is not correct but (R) is correct
- D(A) is correct but (R) is not correct
Correct answer
D. (A) is correct but (R) is not correct
Step-by-step solution
Assertion (A) is correct because the plant families Convolvulaceae and Solanaceae are indeed included in the order Polymoniales. Reason (R) is incorrect because the assignment of these families to the order Polymoniales is based mainly on floral characters, not vegetative characters. In plant taxonomy, floral (reproductive) characters are considered more conservative and reliable than vegetative characters for higher-level classification. Answer: (A) is correct but (R) is not correct
