Explanation:

Twin studies, especially of monozygotic (identical) twins raised apart, show strong genetic links. Identical twins share 100% genes. Research (like Bouchard's Minnesota Study of Twins Reared Apart) indicates genetics (not just shared or non - shared environments) play a major role. Two - thirds attribution aligns with genetic influence findings in personality research.

Answer:

C. genetic influences
