Answer

To answer the question "In catkin, the flowers are," we will analyze the characteristics of catkins and the options provided.

### Step-by-Step Solution:

1. **Understanding Catkin**:
- A catkin is a type of inflorescence that is characterized by a pendulous spike. This means that the flowers are arranged in a way that they hang downwards.
- Catkins are typically found in the leaf axils of certain plants.

2. **Identifying Flower Characteristics**:
- Catkins are known to have **unisexual flowers**, meaning that the flowers are either male or female, but not both.
- The flowers in catkins are **sessile**, which means they do not have a stalk (pedicel) and are directly attached to the main stem.

3. **Evaluating the Options**:
- The options provided are:
- A) Unisexual and sessile
- B) Bisexual and sessile
- C) Unisexual and pedicelate
- D) Bisexual and pedicelate
- From our understanding of catkins, we can eliminate options:
- Option B (Bisexual and sessile) is incorrect because catkins do not have bisexual flowers.
- Option C (Unisexual and pedicelate) is incorrect because the flowers are sessile, not pedicelate.
- Option D (Bisexual and pedicelate) is also incorrect for the same reasons as option B.

4. **Conclusion**:
- The only option that accurately describes the flowers in a catkin is **A) Unisexual and sessile**.

### Final Answer:
The flowers in catkin are **unisexual and sessile**.
