A gravid proglottid of taenia means a segment in which

Options

A. Only female organs are found
B. Both male and female organs are found
C. Only fertilised eggs are present in uterus and all other organs have degenerated
D. Hexacanth embryos have been formed

Answer

### Step-by-Step Solution:

1. **Understanding Gravid Proglottid**: A gravid proglottid refers to a segment of the tapeworm (specifically Taenia) that is filled with eggs. It is a mature segment that has developed reproductive organs.

2. **Presence of Reproductive Organs**: In a gravid proglottid, both male and female reproductive organs are present. This means that the segment can produce fertilized eggs.

3. **Egg Production and Shedding**: The primary function of a gravid proglottid is to produce and shed eggs. When the proglottid is mature, it releases eggs into the environment, which can then infect other hosts.

4. **Evaluating Options**:
- The first option states that only female organs are found. This is incorrect because both male and female organs are present.
- The second option states that both male and female organs are found. This is correct.
- The third option states that only fertilized eggs are present and all other organs are degenerated. This is also correct, as the proglottid primarily contains eggs at this stage.
- The fourth option mentions hexacant embryos, which are not formed in the gravid proglottid stage.

5. **Conclusion**: The most accurate answer is that a gravid proglottid contains both male and female reproductive organs, and it is primarily involved in the production and shedding of fertilized eggs.

### Final Answer:
A gravid proglottid of Taenia means a segment in which both male and female reproductive organs are present, and it is primarily responsible for producing and shedding fertilized eggs.
