In which of the following types the fruits is multilocular and split open longitudinally along dorsal sutures.

Options

A. Septicidal
B. Capsular
C. Loculicidal
D. Septifragal

Answer

To solve the question regarding which type of fruit is multilocular and splits open longitudinally along dorsal sutures, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a type of fruit that is multilocular and splits open longitudinally along the dorsal sutures.

2. **Identifying the Options**: The options provided are:
- 1) Septicidal
- 2) Capsular
- 3) Loculocidal
- 4) Septifetal

3. **Defining the Terms**:
- **Septicidal**: This type of fruit splits along the ventral sutures.
- **Capsular**: A general term for fruits that can split open; they can be further classified into types like septicidal, loculocidal, and septifetal.
- **Loculocidal**: This type of fruit splits open along the dorsal sutures, specifically longitudinally.
- **Septifetal**: This type of fruit has irregular divisions and can split open from any point.

4. **Analyzing Each Option**:
- **Option 1 (Septicidal)**: Splits along ventral sutures, so it cannot be the answer.
- **Option 2 (Capsular)**: While capsular fruits can split, they include various types (septicidal, loculocidal), so it does not specifically answer the question.
- **Option 3 (Loculocidal)**: This type splits open along the dorsal sutures longitudinally, which matches the question's criteria.
- **Option 4 (Septifetal)**: Irregular division, so it does not fit the requirement of splitting along dorsal sutures.

5. **Conclusion**: Based on the analysis, the correct answer is **Option 3: Loculocidal**, as it is the type of fruit that is multilocular and splits open longitudinally along the dorsal sutures.
