C

D
Triploid
Verified step by step guidance1
Understand the terminology related to chromosome sets: 'n' represents one complete set of chromosomes. For example, humans have 2n (diploid), meaning two sets of chromosomes.
Identify the meaning of the prefixes: 'Haploid' means one set (n), 'Diploid' means two sets (2n), 'Triploid' means three sets (3n), and 'Tetraploid' means four sets (4n).
Recognize that a zygote with 3 sets of chromosomes (3n) is called 'Triploid' because it contains three complete sets of chromosomes.
Confirm that the other options do not match the chromosome number: Diploid (2n) is two sets, Haploid (n) is one set, and Tetraploid (4n) is four sets.
Conclude that the correct term for a zygote with 3 sets of chromosomes is 'Triploid'.
