Assertion : Second trimester abortion are much more complicated
Reason : After 12 weeks the foetus becomes intimately assiciated with the maternal tissues.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false

Explanation

To solve the question regarding the assertion and reason about second trimester abortions, we will analyze both statements step by step.

### Step 1: Understanding the Assertion
- **Assertion**: "Second trimester abortions are much more complicated."
- **Analysis**: The assertion refers to the complications that arise during abortions in the second trimester (12 to 26 weeks of pregnancy). It is known that abortions during this period can lead to various complications such as uterine perforation, uterine rupture, and severe hemorrhage. Therefore, this assertion is **true**.

### Step 2: Understanding the Reason
- **Reason**: "After 12 weeks, the fetus becomes intimately associated with the maternal tissues."
- **Analysis**: This statement explains that after 12 weeks of gestation, the fetus is more closely attached to the maternal tissues, specifically the uterine lining. This close association indeed makes the process of abortion more complicated, as detaching the fetus from the maternal tissues can lead to severe complications. Thus, this reason is also **true**.

### Step 3: Evaluating the Relationship Between Assertion and Reason
- Now that we have established that both the assertion and the reason are true, we need to determine if the reason correctly explains the assertion.
- The reason provided explains why second trimester abortions are more complicated: the intimate association of the fetus with maternal tissues makes the procedure riskier and more complex. Therefore, the reason is a **correct explanation** of the assertion.

### Conclusion
- Since both the assertion and the reason are true, and the reason correctly explains the assertion, the final answer is:
**Both assertion and reason are true, and reason is the correct explanation of assertion.**

### Final Answer: Option A
