Explanation:

To determine which part of DNA codes for traits, recall DNA structure:

• Option A: Hydrogen bonds hold DNA strands (not code traits).
• Option B: Carbon count in DNA is not trait - coding.
• Option C: Nucleotide bases (A, T, C, G) sequence in DNA forms genes, which code for proteins/traits.
• Option D: Phosphate sequence is structural, not trait - coding.

Answer:

C. The sequence of nucleotide bases in the DNA molecule.
