The correct answer is option 1 i.e. pursued.

Let's have a look at the meaning of the given options:-

1. pursued- to try to achieve something or to continue to do something over a period of time.
2. carried- to hold somebody/something in your hand, arms or on your back while you are moving from one place to another.
3. persisted- to continue doing something even though other people say that you are wrong or that you cannot do it.
4. sought- to try to find or get something.

For any degree, we use "Pursue" hence, the chosen will suit the given statement.

Hence, the chosen option will be correct.
