To determine the heights of the pea plants based on their genotypes, let's analyze the alleles given:

  • Plant A (tt): This plant has two recessive alleles (short).
  • Plant B (TT): This plant has two dominant alleles (tall).
  • Plant C (Tt): This plant has one dominant allele and one recessive allele. The presence of the dominant allele means that Plant C will also be tall, though likely not as tall as Plant B.

From this analysis, we can conclude:

  1. Plant A (tt) will be the shortest.
  2. Plant B (TT) will be the tallest.
  3. Plant C (Tt) will be tall, but likely shorter than Plant B.

Therefore, the most reasonable prediction based on the genotypes is:

Plant C will be the shortest.
