Answer

To solve the question regarding the assertion and reason about sutures and gomphoses being synarthroses, we can follow these steps:

### Step 1: Understand the Assertion
The assertion states that "Sutures and gomphoses are synarthroses."
- **Explanation**: Synarthroses are joints that are immovable. Sutures are the joints found between the bones of the skull, and gomphoses are the joints between teeth and their sockets. Both types of joints do not allow for movement.

### Step 2: Understand the Reason
The reason states that "Sutures and gomphoses are slightly movable."
- **Explanation**: This statement is incorrect. Sutures and gomphoses are classified as immovable joints, meaning they do not allow any movement at all.

### Step 3: Evaluate the Truth of Assertion and Reason
- The assertion is true because sutures and gomphoses are indeed synarthroses (immovable).
- The reason is false because it incorrectly states that these joints are slightly movable.

### Step 4: Determine the Correct Option
Based on the evaluation:
- The assertion is true, and the reason is false. Therefore, the correct answer is option 3: "Assertion is true and reason is wrong."

### Final Answer
The correct answer is option 3: "Assertion is true and reason is wrong."
