The correct option is c. This is the example of incomplete dominance. Here yellow colour (YY) is incomplete dominant to blue (bb)

When we're looking at genes that code for a particular trait, we use one letter to represent that trait. In this case, we have a gene for feather color which we will use the letter $B$ to represent. We have a pure breeding yellow bird with a genotype of $bb$, and a pure breeding bluebird with a genotype of $BB$. If we put this in a punnet square, with the alleles for the bluebird on the top of the Punnett square and the alleles for the yellow bird on the left of the Punnett square, we get all green offspring.

$\begin{array}{ccc}& B& B\\ b& Bb& Bb\\ b& Bb& Bb\end{array}$

The genotype of the green bird is $Bb$, the yellow bird is $bb$, and the bluebird is $BB$.

Since answers a, b, and d all show a mix of two different genes, the only possible answer would be answer c.
