In a monohybrid cross between two heterozygous tall pea plants (Tt × Tt), what is the probability that an offspring will be homozygous recessive?

A cross between Tt × Tt produces offspring in the ratio 1TT : 2Tt : 1tt. The homozygous recessive (tt) genotype represents 1 out of 4 offspring, giving a probability of 25%. Options B and C represent the heterozygous frequency and the dominant phenotype frequency respectively.
