sir,it can be streptococcus variety, so why bacitracin is not the answer for this question

A infant had high grade fever and respiratory distress at the time of presentation to the emergency room. The sample collected for blood culture was subsequently positive showing growth of a haemolytic colonies. On Gram staining these were gram positive cocci. In the screening test for identification, the suspected pathogen is likely to be susceptible to the following agent:
A) Bacitracin
B) Novobiocin
C) Optochin
D) Oxacillin

because you are suspecting strept pneumoniae as it alpha hemolytic... so optochin sensitivity is the best answer
