Solution

The correct option is A
$N O$

Moderately concentrated nitirc acid gives nitric oxide and nascent oxygen which is a monatomic oxygen radical, which is far more reactive.

$2 H N O_{3} \to N O + 3 [O] + H_{2} O$

While highly concentrated nitric acid gives nitrogen dioxide and a nascent oxygen

$2 H N O_{3} \to N O_{2} + [O] + H_{2} O$
