B $Al_2 O_3, As_2 O_3, CO$ and $NO$
C $K_2 O, Cl_2 O_7, As_2 O_3$ and $NO$
D $Na_2 O, N_2 O, Al_2 O_3$ and $CO$

Correct answer

C. $K_2 O, Cl_2 O_7, As_2 O_3$ and $NO$

Step-by-step solution

K_2O

is a metallic oxide and is basic in nature.

Cl_2O_7

is a non-metallic oxide with a high oxidation state and is acidic in nature.

As_2O_3

is a metalloid oxide and is amphoteric in nature.

NO

is a neutral oxide.

Thus, the set

K_2O, Cl_2O_7, As_2O_3
