On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles

On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:

Muppet hair color as a function of two-locus genotypes
Two-locus genotype Muppet hair color
A_B_ Cookie monster blue
aaB Elmo red
_ bb Janice blonde
If two doubly-heterozygous Cookie-monster blue-haired muppets mate, and produce 1000 children, which of the follow values most closely represents the expected number of Janice blonde-haired offspring? The answer allows for random variation in hair color.
a. 12.
b. 260
c. 252.
d. 512.
e. 240.
