The correct answer among the given options is - LB media

Explanation:

The type of bacteria is unknown so can not be determined precisely what media should be best for such population however, on the given information the best media would be LB media for this population due to the fact that all other media forms that are selective will inhibit its growth and it is a nutrient-rich medium which favors the growth of bacteria.
