Which of the meiotic pairing possibilities in tetraploids and their consequence is correct?

A-chromosomes pair as bivalents, segregate normally producing diploid gametes.

B- Chromosomes pair as quadrivalent, segregates normally producing tetraploid gametes.

C-Chromosome pair as Trivalents form, segregation leads to nonfunctional aneuploid gametes
