Final answer:
B. Strep throat. The doctor would most likely have done a throat culture to check for strep throat. If you have strep throat, you would be prescribed antibiotics.
Step-by-step explanation:
The test that your doctor would most likely have done is a throat culture. This test involves swabbing the back of your throat and sending the sample to a laboratory for analysis.
The doctor would be checking to see if you have streptococcal infection or strep throat. Streptococcal infections are caused by the bacteria Streptococcus pyogenes.
If you do have strep throat, you would be prescribed antibiotics to kill the bacteria and help alleviate your symptoms. The most commonly prescribed antibiotics for strep throat are oral amoxicillin and intramuscular penicillin G.
