The relationship between "horse" and "foal" is that a foal is a young horse, specifically a baby horse. Therefore, when considering the equivalent relationship for "mother," it is essential to identify a term that signifies a young offspring. In this case, "son" represents a young male offspring of a mother.

While "mare" refers to an adult female horse and "stallion" refers to an adult male horse, neither of these options indicates a young animal.
