Solution:

Given information:
- There are five flats, one above the other.
- Five professionals live in these flats.
- Professor has to go up to meet his IAS officer friend.
- Doctor is equally friendly to all and has to go up as frequently as go down.
- Engineer has to go up to meet his MLA friend, above whose flat lives the professor's friend.

To find: The order in which the five professionals live.

Explanation:
- The engineer has to go up to meet his MLA friend, above whose flat lives the professor's friend. So, the engineer's flat must be below the MLA's flat and the professor's flat must be above the MLA's flat.
- The professor has to go up to meet his IAS officer friend. So, the IAS officer's flat must be above the professor's flat.
- The doctor is equally friendly to all and has to go up as frequently as go down. So, the doctor's flat must be in the middle, between the professor's flat and the engineer's flat.

Therefore, the order in which the five professionals live is:
Professor -> Engineer -> Doctor -> MLA -> IAS officer

Hence, option D is the correct answer.
