Given below are figures representing four different situations/examples of genetic and environmental (temperature) effects on plant height in two varieties of a plant species. In figures A, C and D, solid and dashed lines represent the mean values of plant height for the two varieties G1 and G2, respectively. In figure B, the solid and dashed lines overlap.

Given below are four statements explaining the four figures.

i. Plant height is influenced primarily by the genotype of the two varieties.

ii. Variation in plant height is influenced only by the temperature and genotype has no effect.

iii. Genotype and temperature collectively have an additive effect on plant height.

iv. Both genotype and environment have an effect on plant height with the two varieties responding differently to the environment.

Which one of the following options correctly matches the figures and their corresponding explanations?
