Solution

The correct options are
A $N_{2} + \frac{1}{2} O_{2} ⟶ N_{2} O$
B $N_{2} + O_{2} ⟶ 2 N O$
C $F_{2} + \frac{1}{2} O_{2} ⟶ F_{2} O$
The following reactions are endothermic under desired conditions.
(A) $N_{2} + \frac{1}{2} O_{2} ⟶ N_{2} O$
(B) $N_{2} + O_{2} ⟶ 2 N O$
(C) $F_{2} + \frac{1}{2} O_{2} ⟶ F_{2} O$
This is because a large amount of energy must be absorbed to break the bonds between nitrogen and fluorine molecules.
The following reaction is an exothermic reaction under desired conditions.
(D) $C + \frac{1}{2} O_{2} ⟶ C O$
