Answer

To solve the question regarding the assertion and reason about the pelvic girdle and the pubic symphysis, we will analyze each statement step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "The two halves of the pelvic girdle meet ventrally to form the pubic symphysis."
- The pelvic girdle is composed of two hip bones (the ilium, ischium, and pubis), which indeed meet at the front (ventrally) to form the pubic symphysis.
- Therefore, this assertion is **true**.

2. **Understanding the Reason**:
- The reason states that "Pubic symphysis consists of immovable fibrous connective tissue."
- The pubic symphysis is actually a type of joint known as a secondary cartilaginous joint, which allows for slight movement. It is not composed of immovable fibrous connective tissue; rather, it consists of fibrocartilage.
- Therefore, this reason is **false**.

3. **Conclusion**:
- Since the assertion is true and the reason is false, we can conclude that the correct answer is that the assertion is true but the reason is false.

### Final Answer:
- The assertion is true, but the reason is false.
