Basal placentation occurs in an ovary which is

Options

A. unilocular
B. bilocular
C. multiocular
D. lateral

Answer

**Step-by-Step Solution:**

1. **Understanding Basal Placentation**: Basal placentation refers to a type of ovule arrangement in which the ovules are attached at the base of a single locule within the ovary. This means that the ovules originate from the bottom part of the ovary's chamber.

2. **Identifying Locules**: In flowering plants (angiosperms), the ovary can have different numbers of locules. A locule is defined as a chamber within the ovary where ovules develop. The number of locules can vary, leading to classifications such as unilocular (one locule), bilocular (two locules), trilocular (three locules), and multilocular (more than three locules).

3. **Determining the Type of Ovary**: Since basal placentation involves the ovules being attached at the base of a single locule, it implies that the ovary must be unilocular. This is because if there were multiple locules, the ovules would not be exclusively attached to the base of one locule.

4. **Conclusion**: Therefore, the correct answer to the question is that basal placentation occurs in an ovary which is **unilocular**.
