Solution

The correct option is D 4 tall plants and 1 medium-height plant.
Mendelian phenotypic ratio of a Monohybrid cross is 3:1, where three represent the dominant trait while 1 represents the recessive trait. There is no blending inheritance present in Mendelian crosses so, a tall plant crossed with a dwarf plant will either give tall or dwarf plant but not a medium-height plant.
So, the wrong option is '4 tall plants and 1 medium-height plant.'
