The ratio of tall to dwarf plants in the offspring (90:30) indicates a 3:1 phenotypic ratio typical of a cross between two heterozygous tall plants (Tt x Tt). Thus, the parents must have been Tt and Tt.

Genotype of Parents:
To determine the genotype of the parents, we can use the information provided about the offspring.
Cross Between Tall and Dwarf Plants:
- Tall plants are usually represented by the dominant allele "T", while dwarf plants are represented by the recessive allele "t".
- When a cross between tall (TT) and dwarf (tt) plants is performed, all the offspring will be heterozygous (Tt) because the tall plant is homozygous dominant (TT) and the dwarf plant is homozygous recessive (tt).
Analysis of Offspring:
- Out of 120 offspring, 90 were tall and 30 were dwarf.
- This ratio of tall to dwarf plants is 3:1, which is a typical result of a monohybrid cross between heterozygous (Tt) and homozygous recessive (tt) parents.
Genotype of Parents:
- Since the offspring were produced in a cross between tall and dwarf plants resulting in a 3:1 ratio of tall to dwarf plants, the genotype of the parents must be Tt (tall) and tt (dwarf).
- Therefore, the correct answer is option B: Tt and tt.
