Answer:

e. horizontal transfer of genes from a marine bacterium

Explanation:

Horizontal gene transfer is the transfer of genetic material from one independent mature bacterium to another and creates new gene combinations in the recipient bacterium. It mostly occurs between the bacterial of different species and is responsible for the spread of new genetic traits such as antibiotic resistance, digestion of specific substances, virulence, etc.

Transfer of genetic material from the donor to host bacteria can occur in three ways: transformation, transduction, and conjugation. According to the given information, marine Bacteroidetes have enzymes required to digest porphyran and agarose. <em>B. plebeius</em> might have acquired the genes for these enzymes from marine Bacteroidetes by horizontal gene transfer. This resulted in its ability to digest the marine seaweed while its close relative species cannot do so.
