Assertion: A pea plant having violet flowers was crossed with a pea plant with white flowers by a geneticist, he observed violet flowers in the first generation.

The violet flower gene outclasses the white bloom gene. Therefore, even though the first generation inherits the white color gene, the first generation's flowers will all be violet due to the predominance of violet-colored blooms. 

Hence, the correct option is c) A is true, but R is false
