Correct Answer: Option D — Neither 1 nor 2
Both statements are fundamental concepts in organic chemistry:

Statement 1 is Correct: Catenation is the unique ability of an element (most notably carbon) to form long chains or rings by bonding with atoms of the same element through strong covalent bonds. This is why carbon can form such a vast number of diverse organic molecules.

Statement 2 is Correct: Isomerism occurs when two or more compounds have the same molecular formula (the same number and types of atoms) but different structural arrangements. Because their structures differ, their physical and chemical properties often differ as well.
