Best Answer Explained in Below-:

The phrase "live up to" is commonly used in English to indicate that someone meets or fulfills expectations, standards, or a reputation associated with them. In the context of the question "You have got quite a reputation ---," the phrase is implying that there are expectations tied to that reputation, and the correct response is to "live up to" it.

Let's consider the other options:

- **B) live up towards:** This phrase is not standard in English and does not convey a clear meaning in the context of expectations or reputation.

- **C) live up for:** This option is also incorrect because "for" does not appropriately connect the idea of meeting expectations related to a reputation.

- **D) live up on:** Similar to "towards," this phrase does not exist in standard English usage in this context and does not convey the intended meaning.

Overall, "live up to" is the only option that accurately communicates the idea of meeting the reputation one has established, making it the correct choice. This expression is integral in discussions about personal accountability and the expectations placed upon individuals based on their actions or achievements.
