III. Seminal plasma `" "` IV. Semen
Select the correct answer using the codes given below

Options

A. I
B. III
C. I and IV
D. I and II

Answer

To determine the components of seminal fluid, we need to analyze each of the given options:

1. **Spermatozoa**: This is the mature form of sperm and is indeed a component of seminal fluid. It is responsible for fertilization.

2. **Spermatids**: These are immature sperm cells that develop into spermatozoa. However, spermatids are not present in seminal fluid; they are found in the seminiferous tubules during the process of spermatogenesis.

3. **Seminal Plasma**: This is the fluid part of semen that provides the medium for sperm to swim. It contains various enzymes and nutrients that support sperm motility and viability. Seminal plasma is a significant component of seminal fluid.

4. **Semen**: This term is often used interchangeably with seminal fluid. Semen consists of spermatozoa suspended in seminal plasma. Thus, it is a correct component of seminal fluid.

Now, summarizing the components of seminal fluid:
- **Correct Components**: Spermatozoa and Seminal Plasma
- **Incorrect Components**: Spermatids (not in seminal fluid) and Semen (though it is synonymous with seminal fluid, it is not a separate component).

Based on this analysis, the correct components of seminal fluid are:
- I. Spermatozoa (Yes)
- II. Spermatids (No)
- III. Seminal Plasma (Yes)
- IV. Semen (Yes, but it is synonymous with seminal fluid)

Thus, the correct answer is: **I, III, and IV**.
