Answer:
C) Rr Only
Explanation:
The genotype of true breeding red parent plant is "RR" and that of the true breeding white parent plant is "rr". The red parent plant with "RR" genotype will form all the gametes with "R" allele while the white parent plant with "rr" genotype will form all the gametes with "r" allele. The random fusion of these gametes will form all the progeny with "Rr" genotype.
Since "R" is incompletely dominant over "r", the progeny with "Rr" genotype would have pink flowers.
