iv. The endometrium undergoes cyclical changes during the menstrual cycle.

Options

A. i and iv

C. ii, iii and iv
D. i,ii,iii and iv

Answer

To solve the question regarding the correct statements related to the human female reproductive system, let's analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement i: The wall of the uterus has three layers of tissue i.e., mesometrium.**
- **Analysis:** This statement is incorrect. The wall of the uterus consists of three layers: the outer layer is called the perimetrium, the middle layer is the myometrium, and the inner layer is the endometrium. The term "mesometrium" refers to a part of the broad ligament that supports the uterus, not a layer of the uterine wall.

2. **Statement ii: The endometrium is the inner glandular layer that lines the uterine cavity.**
- **Analysis:** This statement is correct. The endometrium is indeed the inner layer of the uterus and is glandular in nature. It plays a crucial role during the menstrual cycle and in pregnancy.

3. **Statement iii: Myometrium is the middle thick layer of smooth muscle which exhibits strong contraction during delivery of the baby.**
- **Analysis:** This statement is correct. The myometrium is the thick middle layer of the uterus composed of smooth muscle, and it is responsible for the contractions during childbirth.

4. **Statement iv: The endometrium undergoes cyclical changes during the menstrual cycle.**
- **Analysis:** This statement is correct. The endometrium undergoes cyclical changes in response to hormonal fluctuations during the menstrual cycle, preparing for potential implantation of an embryo.

### Conclusion:
The correct statements are:
- Statement ii (The endometrium is the inner glandular layer that lines the uterine cavity.)
- Statement iii (Myometrium is the middle thick layer of smooth muscle which exhibits strong contraction during delivery of the baby.)
- Statement iv (The endometrium undergoes cyclical changes during the menstrual cycle.)

Thus, the correct options are statements ii, iii, and iv.
