Optimal recovery and identification of anaerobic bacteria in clinical specimens occurs when:

A) the initial incubation period is at 35° to 37° C for 48 hours.
B) plates are incubated for at least 3 days before discarding as negative.
C) the initial incubation period is at 35° to 37° C for 24 hours.
D) thioglycollate broth can be inspected daily for 3 days.
