Assertion: Family has a group of related orders and classes.
Reason: Families are characterised on the basis of only vegetative characters not by reproductive characters:

Options

A. If both assertion and Reason are true and the reason is a correct explanation of the assertion.
B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion and Reason are False.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Family has a group of related orders and classes." In biological classification, the taxonomic hierarchy is structured as follows: Kingdom > Phylum/Division > Class > Order > Family > Genus > Species. Therefore, the family is a rank that is below the order and class, which makes the assertion incorrect.

2. **Evaluating the Reason**: The reason provided states that "Families are characterized on the basis of only vegetative characters not by reproductive characters." This statement is also incorrect. In taxonomy, both vegetative (non-reproductive) and reproductive characteristics are used to classify and characterize families. Hence, the reason is false.

3. **Conclusion**: Since both the assertion and the reason are false, the correct answer to the question is that both the assertion and reason are false.

**Final Answer**: Both Assertion and Reason are false.
