D. Species with an odd number of chromosome sets (triploid and pentaploid) would be infertile.
E. Aneuploid individuals (monosomic and trisomic) would have reduced fertility.
Explanation - Chromosomes generally happens to occur in the set of two. Organism that have more than two sets of chromosome are called polyploids. Polyploids that have odd or uneven count of sets of chromosome are sterile or fully infertile.
Example - triploid (3n), pentaploid (5n) because their gametes and offsprings are aneuploid. Aneuploidy is addition of entire chromosome to the already existing normal set of chromosome. Aneuploids are unable to produce viable offspring because their fertility got decreased as the zygote formed after the fertilization itself is aneuploid.
