A Correct answer
Explanation

Allotropes are different structural forms of the same element in the same physical state. Carbon exists as diamond, graphite, and amorphous carbon - all allotropes with different arrangements of carbon atoms. Isomers are molecules with the same formula but different structure, isomorphs are crystals with similar form but different composition, and isotopes are atoms with different numbers of neutrons.
