C Correct answer
Explanation

Mendel's 'factors' - the hereditary units that controlled traits in his pea plants - are now known as genes. Mendel discovered and described these units without any knowledge of DNA, chromosomes, or molecular biology. His 'factors' correspond exactly to what we now understand as genes: segments of DNA that code for specific traits.
