Colorblindness, being a recessive trait located on the X chromosome, is inherited in a specific way based on the genetic contributions from the mother and father.
A man has one X chromosome (from his mother) and one Y chromosome (from his father). Since colorblindness is recessive, a man will express colorblindness if he inherits the colorblind allele (the recessive trait) on his X chromosome.
Therefore, the man received the colorblind trait from his **mother** (option A), as she is the source of his X chromosome. The father contributes the Y chromosome, which does not carry the trait for colorblindness.
