By checking the value in answer column it should return content from that column here answer is C so it should get Delhi from column C and put it in output column
As Davesexcel stated, it seems HLOOKUP could work.
Here is a Google Sheet using HLOOKUP with a formula that should work in Excel as well: https://docs.google.com/spreadsheets/d/1LaCqkcLpgiQ1cYZEUBSSYbJkOaht1A34Af1MlZJwIc0/edit?usp=sharing.
The formula I have as an example is:
=hlookup(F2,B1:E2,row())
