Answer
Both A and R are true but R is not the correct explanation of A.
Explanation — Carbon has a strong tendency to form bonds with other carbon atoms, resulting in long chains, branched chains, and rings. This is called catenation. Hence, the assertion (A) is true.
Catenation means the ability of atoms to link with themselves via covalent bonds. Hence, the reason (R) is true.
However, the reason explains what is catenation, but it doesn't explain why carbon shows catenation property. The actual reason why carbon shows strong catenation is due to its small atomic size and the strength of the C–C bond, which makes these chains stable. Hence, reason (R) is not the correct explanation of assertion (A).
