Solution

The correct option is A

First, check out for bond order.

F - F $\Rightarrow$ Bond order = 1

O = O $\Rightarrow$ Bond order = 2

N ≡ N $\Rightarrow$ Bond order = 3

H - H $\Rightarrow$ Bond order = 1

Now, as F, N and O are from same period and we know that

$B o n d o r d e r \propto \frac{1}{B o n d l e n g t h}$
Therefore, $N_{2} < O_{2} < F_{2}$

And H - H bond length will be least because H is very small compared to second period elements.

$\Rightarrow$ For bond length

$F_{2} > O_{2} > N_{2} > H_{2}$
