(b) Purple and White
Explanation:
In pea plants, the flower colour character has two contrasting traits: purple and white. Among these, purple flower colour is dominant, meaning it is expressed even when inherited in one copy. White flower colour is recessive and is expressed only when both alleles are for white flowers (homozygous recessive). This dominant-recessive inheritance pattern was first discovered by Gregor Mendel in his classic experiments on pea plants, forming the basis of Mendelian genetics.
