Option 2 : R2D2 is the only robot which can repair aeroplanes.

There are two facts. R2D2 is a robot who can repair aeroplanes and no other robot can do this work. The other functions of R2D2 is not known and thus inference 1 does not follow.

We do not know whether R2D2 can repair anything else other than aeroplanes. Thus option 3 does not follow.

There can be other robots and thus option 4 is eliminated.

Only option 2 is the logical inference that follows.
