Im stuck on this HW Eq. question (Chap 7, Q 7). Can someone explain why the answer choice is not A?

Why can't you work this problem like question 6?
 
Could you write out the question/answer choices? I don't have the book on hand anymore, but I'll try to help you with the explanation.
Thank you so much for your response! I actually ended up figuring it out but for your curiosity it was a HW equilibrium question:

After test-cross experiments, it was determined that the frequencies of homozygous dominant, heterozygous, and homozygous recessive individuals for a particular trait were 32%, 64%, and 4% respectively. The dominant and recessive allele frequencies

A. are 0.2 and 0.8, respectively
B. are 0.32 and 0.68, respectively
C. are 0.36 and 0.64, respectively D. are 0 32 . and 1 0 32 - . , respectively
E. cannot be determined because the population is not in Hardy-Weinberg equilibrium
