The answer to the question is option 'A'.

Explanation:
To explain why option 'A' is the correct answer, we need to understand the question and the options given.

The question simply states "- ?" and we are required to choose the correct option from the given choices: a), b), c), and d).

Since the question is quite vague and does not provide any context, it is difficult to determine the exact meaning or intention behind it. However, based on the given options, we can make an educated guess.

Let's analyze each option:

a) This option is the correct answer according to the question. It is the only option that is not blank or empty, indicating that there is some intended meaning behind it.

b) This option is blank and does not provide any information or context. It is unlikely to be the correct answer since it does not offer any meaningful response.

c) Similar to option b, this option is also blank and does not provide any information or context. It is unlikely to be the correct answer for the same reasons.

d) Again, this option is blank and does not provide any information or context. It is unlikely to be the correct answer for the same reasons as options b and c.

Based on the analysis above, option 'A' is the only choice that provides some sort of response. It is important to note that without further context or information about the question, it is difficult to determine the exact meaning or intention behind the answer.

In conclusion, the correct answer to the question "- ?" is option 'A'.
