Numerous pure breeding crosses are made between two inbred plant strains, one having a mean height at maturity of 96 cm and the other as 56 cm. The height of the F1 progeny at maturity averages close to 76 cm. Height of plant control by four pair of polygene. The F2 progeny show the following phenotype.

When sufficient heat is applied, double-stranded DNA denatures into two single-stranded molecules as the heat breaks all of the hydrogen bonds. In an experiment, molecules of single-stranded DNA from species X are separately hybridized with putatively homologous single-stranded DNA molecules from five species (A-E). The hybridized DNAs are then heated, and the temperature at which complete denaturation occurs is recorded. Based on the data below, which species is probably most closely related to species X?
