Solution

The correct option is A True
In basic medium means there will be an attack by a proton and the aniline is protonated to anilinium ion.
$C_{6} H_{5} - N H_{2} a n i l i n e p r o t o n a t i o n - ------ \to C_{6} H_{5} N H_{3}^{+} a n h i l i n i u m i o n$
Anilinium ion due to the positive charge on it shows -I effect so it will not remain as O, P-directing towards strong acid. It will behave as meta-directing as -I effect is more on ortho(O) and para (P) position and less on meta so when an electrophile attacks, it attacks faster on meta- position.
