Hi there! I think the answer to your question is either E or B
Semen is the correct answer

Hope this helps!

Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
