Consider the following sets of reproductive terms.
1. Sperm - oviduct, egg - uterus
2. Ovulation - egg, oviduct - uterus
3. Sperm - testis , spermduct - penis
4. Menstruation - egg, oviduct - uterus
The sets of correct combination are

Options

A. 1, 2 and 3
B. 2, 3 and 4
C. 3, 4 and 1
D. 1, 2 and 4

Explanation

To solve the question regarding the sets of reproductive terms, we need to analyze each set carefully to determine which combinations are correct.

### Step-by-Step Solution:

1. **Set 1: Sperm - Oviduct, Egg - Uterus**
- Sperm is released into the oviduct (fallopian tube) where it can fertilize the egg. However, the egg develops in the ovary and is not directly associated with the uterus until after fertilization. Therefore, this set is **incorrect**.

2. **Set 2: Ovulation - Egg, Oviduct - Uterus**
- Ovulation refers to the release of an egg from the ovary. The egg then travels through the oviduct (fallopian tube) towards the uterus. This set accurately describes the process of ovulation and the path of the egg, making it **correct**.

3. **Set 3: Sperm - Testis, Spermduct - Penis**
- Sperm is produced in the testis and travels through the sperm duct (vas deferens) to the penis for ejaculation. This set correctly describes the male reproductive pathway, hence it is **correct**.

4. **Set 4: Menstruation - Egg, Oviduct - Uterus**
- Menstruation is the shedding of the uterine lining and unfertilized egg. The egg does not travel to the oviduct during menstruation; rather, it is expelled from the uterus. Therefore, this set is **incorrect**.

### Conclusion:
The sets of correct combinations are **Set 2 and Set 3**.

### Final Answer:
The correct combinations are **2 and 3**.
