Final Answer : C, Explanation :  When two hybrids are crossed (Rr x Rr), there is a 25% chance of getting an offspring with two copies of the recessive allele (rr), which results in white flowers. There is also a 50% chance of getting an offspring with one copy of R and one copy of r (Rr), which results in pink flowers. Therefore, the chances of getting an offspring with pink flowers are 50%.
