B Correct answer
Explanation

Solanum has a basic chromosome number of x=12. A pentaploid (5x) would therefore have 5×12=60 chromosomes. Pentaploids are rare and usually sterile due to irregular meiosis, but can occur through hybridization events. This contrasts with hexaploid wheat (6x=42) or other polyploid crops.
