Answer 1

The Correct Option is D

To solve this question, we need to identify the structures present specifically in the female cockroach from the given options.

1. Collateral gland: This gland is found in female cockroaches and is involved in the production of substances that help in forming and protecting the ootheca, which the female uses to encase her eggs. Therefore, this is present in females.
2. Mushroom gland: This gland is found in male cockroaches. It secretes a seminal fluid that helps in sperm transfer. It is not present in females.
3. Spermatheca: This is a sac-like structure found in female cockroaches where sperm is stored after mating. Hence, it is present in the female.
4. Anal style: This is a paired appendage found only in male cockroaches, used for copulation and reproductive purposes. It is absent in females.
5. Phallic gland: This gland is also found in male cockroaches and is associated with the reproductive system. It is not present in females.

After analyzing all the options, it is evident that the organs found in female cockroaches are the Collateral gland (A) and the Spermatheca (C).

Therefore, the correct answer is: A and C only.
