The other options are:
- B. could not – This is the past tense of “cannot”. It means that a man was not able to travel in a ladies compartment in the past.
- C. shall not – This is a formal way of saying “must not”. It means that a man is not allowed to travel in a ladies compartment.
- D. will not – This is a future tense of “will not”. It means that a man is not going to travel in a ladies compartment in the future.
The reason why “cannot” is the correct answer is because it is the most direct and concise way of saying that a man is not allowed to travel in a ladies compartment. The other options are either too formal, too vague, or too tentative.
It is important to note that the rules about who can and cannot travel in a ladies compartment may vary depending on the country or region.
