Agamete has select one:
a. one copy of each chromosome. it is haploid.
b. two copies of each chromosome. it is haploid
c. one copy of each chromosome. it is diploid.
d. two copies of each chromosome. it is diploid.

A gamete has one copy of each chromosome, it is haploid. 
A gamete is a haploid cell produced during the process of meiosis, it fuses with another haploid cell during fertilization in sexual reproduction. May be therefore described as mature haploid (single copy of chromosome) male or female germ cell that unites with another haploid cell and forms a zygote.
