A
42 pm
loader
B
39 pm
loader
C
41 pm
loader
D
48 pm
loader

Solution

The correct option is D 48 pm
Atomic radii of fluorine is 42 pm. Atomic radii of oxygen is 48 pm. In moving from left to right across a period, the atomic radius decreases as the effective nuclear charge increases. Hence, fluorine has smaller atomic radius than oxygen.
