Assertion: The development in cockroach is heterometabolous metamorphosis.
Reason: Young ones resemble the adults in all characters.

Options

A. If both Assertion and Reason are true and Reason is correct explanation of Assertion.
B. If both Assertion and Reason are true but Reason is not correct explanation of Assertion
C. If Assertion is true but Reason is false
D. If both Assertion and Reason are false

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "The development in cockroach is heterometabolous metamorphosis." We need to evaluate if this statement is true or false.

2. **Definition of Heterometabolous Metamorphosis**: Heterometabolous metamorphosis refers to a type of development where there are distinct larval stages that do not resemble the adult form. This is typically seen in insects like butterflies.

3. **Cockroach Development**: In contrast, cockroaches undergo hemimetabolous metamorphosis, which is characterized by incomplete metamorphosis. In this type, the young ones (nymphs) resemble the adults but are smaller and lack fully developed wings.

4. **Evaluating the Reason**: The reason given is "Young ones resemble the adults in all characters." This statement is also incorrect because while nymphs do resemble adults, they do not possess all adult characteristics, such as wings.

5. **Conclusion**: Since both the assertion and reason are incorrect, we conclude that both statements are false.

6. **Identifying the Correct Option**: Based on the evaluation, the correct option is that both assertion and reason are false.

**Final Answer**: Both assertion and reason are false.
