In a compound, the total valence is zero. If (number of carbon atoms) : (number of oxygen atoms) = 1 : 1, the total valence will be zero. Hence, the formula is in the form of CₙOₙ. Among the four option, only CO is in the form of CₙOₙ.
The answer: 1. CO
The answer: 1. CO

Correct formula .........
+2-2 ........ oxidation states....
..CO
The "mon-" in carbon monoxide indicates 1 oxygen. Compare to CO2, carbon dioxide.

The prefix, mono, means one. So this compound has one oxygen atom. CO is the correct answer.
OR
C+2 + O-2 = CO 0
OR
C+2 + O-2 = CO 0
