• A.
• B.
• C.
• D.

Answer 1

The correct option is C

For a stable resonating structure, octet should be complete for all the elements and same charges should not be adjacent to each other.
In (b),(c), and (d) unlike charges are adjacent to each other whereas in (a) like charges are adjacent to each other which makes the structure (a) unstable and hence incorrect
