Answer

To solve the question regarding the correct information about the American cockroach (Periplaneta americana), let's analyze each option step by step.

### Step-by-Step Solution:

1. **Option 1: Head is epigonathus condition.**
- The term "epigonathus" refers to a head position that is oriented downward, which is not the case for the American cockroach. Instead, the correct term for the head of a cockroach is "hypogonathus," meaning the head is bent at a right angle to the main body axis.
- **Conclusion:** This option is incorrect.

2. **Option 2: Head having ten chambers.**
- The head of the American cockroach consists of six segments, not ten. Each segment contributes to the structure and function of the head, but there are not ten chambers present.
- **Conclusion:** This option is also incorrect.

3. **Option 3: Male Malpighian tubules 50 to 60 numbers.**
- Malpighian tubules are excretory structures in cockroaches, but the number of Malpighian tubules in a cockroach is around 150, not 50 to 60. They are located at the junction of the midgut and hindgut.
- **Conclusion:** This option is incorrect as well.

4. **Option 4: Anal saccae help in copulation.**
- Anal saccae are indeed present in both male and female cockroaches. They serve a sensory function and play a role in the copulation process, making this statement accurate.
- **Conclusion:** This option is correct.

### Final Answer:
The correct information about the American cockroach (Periplaneta americana) is found in **Option 4: Anal saccae help in copulation.**
