B is the answer.
Why? The blue form of the trait was hidden in both parents but showed up in the child. Any trait that can be hidden and show up later must be recessive.
Why do both parents have to be carriers? Anyone with a recessive trait must have two copies of the recessive form of the gene. That means the child got one copy of the recessive allele from each parent.
