Explanation:
Hey there!
In (a) part let us take the value of n as 1 first.
n + 2
=> 1+2
= 3
But it doesn't get matched with t.
So, (a) option cancelled.
In (b) part, let us take the value of n as 1.
n - 2
=> 1 - 2
= -1
But this also didn't match with t.
Option (b) cancelled.
In (c) part, let us take the value of n as 1.
n × 2
=> 1 × 2
= 2
Matched! Let us check further. Taking value of n as 2,
=> 2 × 2
= 4
Matched again! So, (c) part is the correct answer.
Let us take the value of n as 1. (For both option (d) and (e))
n + 3
=> 1 + 3
= 4 (wrong)
n + 4
=> 1 + 4
= 5 (wrong)
So, (c) part is the right answer.
Hope it helps :)
