Answer:
D (3/4)
Explanation:
This cross involves a single gene coding for flower colour in pea plant where the purple allele (P) is dominant over the white allele (p) since the purple allele masks the expression of the white allele in a heterozygous state (Pp). A cross between two heterozygous plants (Pp) will produce four possible offsprings with genotypes PP, Pp and pp in the ratio 1:2:1.
The PP and Pp genotypes are purple flowered while the pp is white flowered. Hence, the probability of having purple flowered plants from this cross is 3 out of 4 i.e. 3/4.
