To analyze the genotypes of the three plants with respect to height:

  • Plant A has the genotype tt (homozygous recessive), which typically represents short height in pea plants.
  • Plant B has the genotype TT (homozygous dominant), which typically represents tall height.
  • Plant C has the genotype Tt (heterozygous), which typically also represents tall height, as the presence of at least one dominant allele (T) will result in a tall phenotype.

Based on this genetic information:

  • Plant A will be the shortest because it has the recessive genotype (tt).
  • Plants B (TT) and C (Tt) are likely to be tall.

The most reasonable prediction is therefore:

Plant A will be the tallest. (This option is incorrect based on our analysis.)

The correct interpretation from the choices given would be:

Plant C will be the shortest. (This option is also incorrect, based on our analysis.)

Ultimately, the correct statement based on the genotypes should be:

Plant A will be the shortest while both Plant B and Plant C will be tall.

However, since this option was not presented, the best understanding can be that Plant B and Plant C will have similar heights (as both are tall).

Thus, the most reasonable prediction based on the initial options you provided is:

Plant B and Plant C will have similar heights.
