3 - follow and following something like that

here interviewer given this and now you have to explain everything thing very precisely, don't be a generic, like these 2-3 options are there just to go what you are gonna do for this directely and then don't go even a single bit off the track as interview was not at all that friendly (he/she said directly that is not what i asked) and interviewer was not open for any discussion, you just keep explaning.

so prepare better and be very concise with your answer.
