Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 24 lists: 'Carbon is only member of the group that can form π bonds. Explains the formation of >C=C<, >C=O,- C=N bonds.' It also states 'Carbon cannot expand its octet.' and 'Carbon forms gaseous oxides, CO and CO₂.'

Hint

Consider the ability of elements to form multiple bonds and the stability of these bonds with smaller atomic sizes.
