A Recently Identified Organism Produces Methane When Provided with Glucose

A recently identified organism produces methane when provided with glucose in the absence of oxygen.This means the organism is

A) capable of aerobic catabolism and uses sulfate in place of oxygen as its terminal electron acceptor.
B) capable of anaerobic catabolism and uses carbon dioxide in place of oxygen as its terminal electron acceptor.
C) capable of aerobic catabolism and uses carbon dioxide in place of oxygen as its terminal electron acceptor.
D) capable of anaerobic catabolism and uses acetate in place of oxygen as its terminal electron acceptor.
E) capable of aerobic catabolism and uses acetate in place of oxygen as its terminal electron acceptor.
