If a man is heterozygous (aa) for a trait, predict his possible sperm.
a. his sperm would not carry either of the alleles.
b. 100% of his sperm would carry both of the alleles (aa)
c. 50% would carry a dominant
a. and 50% would carry a recessive
a. d. 50% would carry two dominant alleles (aa) and 50% would carry two recessive alleles (aa)

The answer is c. 50% would carry a dominant A and 50% would carry a recessive a.

Sperm is a male gamete and as it is known gametes are haploid cells. Haploid cells have only one allele in the loci. So a man heterozygous (Aa) for some trait will have in his sperm either allele A or allele a. The chance to have either one of them is 50% since there are only two options.
