Plant A will be the tallest. Since plant A is homozygous dominant for height (TT), it will exhibit the dominant trait for tall height. Plant B is also homozygous dominant and will be tall, but plant A will likely be taller. Plant C is heterozygous for height (Tt) and will have a height somewhere in between the homozygous dominant and recessive plants.
