I think it can be C or D. But I think it's D.
Answer:
a) The allele frequencies are - 
b) Genotype frequencies for this population- 
Explanation:
Given ,
Red color of flower is dominant to white color flower
Let "R" represents allele for red color and "r" represents allele for white color
out of
flower,
are red flowers.
So the frequency of red flowers with genotype "RR" is equal to

As per hardy Weinberg's I equilibrium equation -

a) The allele frequencies are - 
Frequency of genotype "rr" i.e homozygous recessive white flower is

Substituting the values of
and
, in below equation, we get -

b) Genotype frequencies for this population- 
Mitosis division occurs in body cell
I think it’s A (low water content foods)
Explanation:
The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
