Correct Answer - Option 4 : Both (2) and (3)
Explanation:
Main statement: Unless I score well, I will not get selected
The meaning which we can conclude is selection is only going to happen when the score is well.
Option 1: I was not selected, means I did not score well. This cannot be implied from the statement maybe there must be some other reason for not selection.
Option 2: I am selected implies I scored well. If someone is selected then he must have scored well.
This can be implied from the statement.
Option 3: I did not score well, means I will not be selected. If someone did not score well then he will definitely not get selected. This can be implied from the statement.
Hence both option 2 and 3 are right. Therefore Option 4 is the right answer.
