A) ¼ tall; ½ intermediate height; ¼ short
B) ½ tall; ¼ intermediate height; ¼ short
C) ¼ tall; ¼ intermediate height; ½ short
D) All tall offspring
E) All intermediate-height offspring

In incomplete dominance, the heterozygous phenotype (Tt) is a blend of the two homozygous phenotypes. Crossing two Tt plants would produce offspring with a 1:2:1 ratio of TT:Tt:tt, translating to ¼ tall (TT), ½ intermediate height (Tt), and ¼ short (tt).
