Solution
The correct option is A Tall
When the dominant and recessive allele is present in an organism, the condition is said to be heterozygous. In such conditions, the dominant allele is always expressed and the recessive allele is masked. Considering this example, the allele for tallness is dominant and hence the plant will be tall.
