Solution

The correct option is B Tetracycline resistance
The cloning vector requires the presence of a selectable marker, which helps in identifying and eliminating non-transformants and selectively permitting the growth of the transformants.
E.coli has two antibiotic resistance genes as selectable markers- ampicillin resistance gene and tetracycline resistance gene.

Antiobiotic resistance gene present on Bam HI site of a E.coli is -tetracycline resistance.
