Assertion (A) : Diaphragms are contraceptive devices used by the male.
Reason ( R): These devices are made of rubber that is used to cover the cervical region.

Options

A. Both assertion (A) and reason ( R) are true and reason ( R) is the correct explanation of assertion (A).
B. Both assertion (A) and reason ( R) are true but reason ( R) is not the correct explanation of assertion (A).
C. Assertion (A) is true but reason ( R) is false.
D. Assertion (A) is false but reason ( R) is true.

Explanation

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step 1: Understand the Assertion
The assertion states: "Diaphragms are contraceptive devices used by the male."
- This statement is incorrect. Diaphragms are actually contraceptive devices that are used by females, not males. They are designed to cover the cervix to prevent sperm from entering the uterus.

### Step 2: Understand the Reason
The reason states: "These devices are made of rubber that is used to cover the cervical region."
- This statement is correct. Diaphragms are indeed made of rubber or silicone and are used to cover the cervical region in females to prevent pregnancy.

### Step 3: Analyze the Relationship between Assertion and Reason
- Since the assertion is false and the reason is true, we conclude that the assertion does not support the reason.

### Conclusion
Based on the analysis:
- Assertion (A) is false.
- Reason (R) is true.

Thus, the correct answer is that A is false but R is true.

### Final Answer
The answer is: Option D - A is false but R is true.
