Assertion. Flowers are trimerous in family Solanaceae.
Reason. Stamens are three in number and carpels are six in number.

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

To solve the question, let's break it down step by step.

### Step 1: Understanding the Assertion
The assertion states that "Flowers are trimerous in family Solanaceae."
- **Definition of Trimerous**: Trimerous refers to floral parts that are in multiples of three (3). This includes petals, sepals, and other floral structures.

### Step 2: Evaluating the Assertion
In the family Solanaceae, flowers are typically described as pentamerous, meaning they have floral parts in multiples of five (5).
- **Conclusion**: The assertion is **false** because flowers in the Solanaceae family are not trimerous; they are pentamerous.

### Step 3: Understanding the Reason
The reason states that "Stamens are three in number and carpels are six in number."
- **Stamens**: In many Solanaceae flowers, there are usually five stamens.
- **Carpels**: The number of carpels can vary, but it is typically not six in the context of the Solanaceae family.

### Step 4: Evaluating the Reason
Since the number of stamens is not three (it is usually five) and the number of carpels is not six, the reason provided is also **false**.

### Step 5: Conclusion
Both the assertion and the reason are false. Therefore, the correct answer to the question is that both the assertion and the reason are false.

### Final Answer
Both the assertion and the reason are false.
