D. Triploid

Answer: Option B

Solution(By Examveda Team)

The ploidy level of Triticum aestivium is Hexaploid.
Aestivum (2n = 6x = 42; AABBDD genome) is an allohexaploid that was formed through hybridization and successive chromosome doubling of three diploid Triticum/Aegilops species.
Hexaploid wheat possesses 42 chromosomes derived from its three ancestral genomes. The 21 pairs of chromosomes can be further divided into seven groups of six chromosomes, based on the similarity of their gene order.
