Answer 1

Answer:

Correct option is A

A resonance structure in which a positive charge is present on the most electronegative atom is highly unstable. Since (III) has a positive charge on the oxygen atom, which has a higher electronegativity than carbon, it is unstable when compared to (I) and (II).
