D. Assertion is false, but reason is true statement.

Answer

To solve the question, we need to analyze the assertion and the reason provided:

### Step 1: Understand the Assertion
The assertion states that "Progesterone is essential for maintenance of the endometrium."
- Progesterone is a hormone produced by the corpus luteum after ovulation.
- Its primary role is to prepare the endometrium (the inner lining of the uterus) for a potential pregnancy by making it thick and rich in blood vessels.

### Step 2: Understand the Reason
The reason states that "Endometrium is essential for implantation of embryo."
- The endometrium is indeed crucial for the implantation of a fertilized egg (embryo).
- After fertilization, the embryo travels to the uterus and implants itself into the endometrium, which provides the necessary nutrients and support for the developing embryo.

### Step 3: Evaluate the Relationship Between Assertion and Reason
- Both the assertion and reason are correct statements.
- However, the reason provided does not directly justify the assertion. The assertion is about the role of progesterone in maintaining the endometrium, while the reason discusses the importance of the endometrium for implantation.

### Conclusion
- Both the assertion and reason are true, but the reason is not the correct explanation for the assertion.

### Final Answer
- The assertion is true, and the reason is true, but the reason does not explain the assertion.
