Answer

To solve the question of picking the odd one out from each series, we will analyze each group of terms step by step.

### Step-by-Step Solution:

**(i) Scrotum, Rate Testis, Fallopian Tube, Vas Deferens**
1. **Identify the structures**:
- Scrotum: Male reproductive structure that holds the testes.
- Rate Testis: Part of the male reproductive system involved in sperm transport.
- Fallopian Tube: Female reproductive structure where fertilization occurs.
- Vas Deferens: Male reproductive duct that transports sperm.
2. **Determine the odd one out**:
- Fallopian Tube is the only female reproductive structure; the others are male.

**Odd one out: Fallopian Tube**

**(ii) Ovary, Uterus, Vagina, Ejaculatory Duct**
1. **Identify the structures**:
- Ovary: Female reproductive organ that produces eggs.
- Uterus: Female reproductive organ where a fertilized egg develops.
- Vagina: Female reproductive canal leading to the outside.
- Ejaculatory Duct: Male reproductive duct that carries sperm.
2. **Determine the odd one out**:
- Ejaculatory Duct is the only male reproductive structure; the others are female.

**Odd one out: Ejaculatory Duct**

**(iii) Acrosome, Graafian Follicle, Corpus Luteum, Cervix**
1. **Identify the structures**:
- Acrosome: Cap-like structure on the head of sperm that aids in fertilization.
- Graafian Follicle: Structure in the ovary that contains the developing egg.
- Corpus Luteum: Structure that forms in the ovary after ovulation.
- Cervix: Lower part of the uterus that opens into the vagina.
2. **Determine the odd one out**:
- Acrosome is associated with sperm (male), whereas the others are female reproductive structures.

**Odd one out: Acrosome**

**(iv) Prostate, Testis, Seminal Vesicles, Cowper's Gland**
1. **Identify the structures**:
- Prostate: Male accessory gland that produces fluid for semen.
- Testis: Primary male reproductive organ that produces sperm.
- Seminal Vesicles: Male accessory glands that produce seminal fluid.
- Cowper's Gland: Male accessory gland that produces pre-ejaculatory fluid.
2. **Determine the odd one out**:
- Testis is the primary reproductive organ, while the others are accessory glands.

**Odd one out: Testis**

### Final Answers:
1. (i) Fallopian Tube
2. (ii) Ejaculatory Duct
3. (iii) Acrosome
4. (iv) Testis

### Correct Option:
The correct option that includes all the odd ones out is option 4.
