The table shows the number of chromosomes per cell for several crop plants. Each of the crop plants was bred from a wild ancestor over many generations. The table also shows the likely haploid number for the wild ancestors. The table shows five polyploid crops, their probable ancestral haploid numbers (PAHN), and the number of chromosomes they have. The domestic oat has 42 chromosomes, with a PAHN of 7; the peanut has a PAHN of 10 and 40 chromosomes. Sugar cane has a PAHN of 10 and 80 chromosomes. Banana had a PAHN of 11 and 22 or 33 chromosomes, and cotton has a PAHN of 13 and 52 chromosomes.

Which conclusion is MOST STRONGLY supported by the data in the table?

A. Plants develop polyploidy only through selective breeding, and not natural processes.
B. Plants may naturally increase their ploidy levels with each generation.
C. Plants can survive 3, 4, or 5 times the haploid number of chromosomes, but not greater ploidy levels.
D. Introducing polyploidy to plants can increase certain desirable or beneficial traits.
