Answer

To solve the question regarding the assertion and reason about Taenia solium, we will follow these steps:

### Step 1: Analyze the Assertion
- The assertion states that "Alimentary canal is absent in Taenia solium."
- This statement is **true**. Taenia solium, commonly known as the pork tapeworm, does not have an alimentary canal. Instead, it absorbs nutrients directly through its skin from the host's digestive system.

### Step 2: Analyze the Reason
- The reason states that "Taenia solium is an endoparasite."
- This statement is also **true**. Taenia solium is indeed an endoparasite, meaning it lives inside the host's body, specifically in the intestines of pigs and sometimes humans.

### Step 3: Determine the Relationship Between Assertion and Reason
- The assertion is true, and the reason is also true. However, the reason does not explain the assertion. The absence of an alimentary canal in Taenia solium is due to its mode of feeding (saprozoic), not solely because it is an endoparasite.

### Step 4: Choose the Correct Option
- Based on the analysis, the correct option is:
- **Assertion and reason are true, but the reason is not the correct explanation of the assertion.**

### Final Answer
The correct answer is Option 2: "Assertion and reason are true, and reason is not the correct explanation of assertion."
