Use the table to answer the question.

To determine the most reasonable prediction about the heights of the three pea plants based on their genotypes, we should first understand the genetics involved.

- The alleles for height are represented by:
- "T" (dominant allele for tall)
- "t" (recessive allele for short)

Based on the provided genotypes:
- Plant A: tt (homozygous recessive) - will be short
- Plant B: TT (homozygous dominant) - will be tall
- Plant C: Tt (heterozygous) - will be tall since the dominant T allele is present

Now we can analyze the predictions:
1. **Plant C will be the shortest.** - This is incorrect because Plant C has at least one dominant T allele.
2. **Plant B and Plant C will have similar heights.** - This is reasonable because both are tall (Plant B is TT and Plant C is Tt).
3. **Plant A will be the tallest.** - This is incorrect because Plant A is tt and will be the shortest.
4. **Plant A and Plant C will have similar heights.** - This is incorrect because Plant A (tt) will be short, while Plant C (Tt) will be tall.

The most reasonable prediction is:
**Plant B and Plant C will have similar heights.**
