This is NOT any homework or anything, so please don't assume. My AP exam is coming up and I'm doing all I can to prepare, and I was reviewing some of my book today and seem to be stuck on these few questions.
Could anyone help me out? on any of them?

A. 4
B. 8
C. 16
D. 32
E. 64
In a trihybrid cross between two individuals that are heterozygous for three traits, what proportion of the offspring will be homozygous recessive for all three traits? Use the rules of probability to determine the answer.
A. 1/8
B. 1/16
C. 1/32
D. 1/64
E. Cannot be determined based on the data given
