Answer #1

ANSWER : The correct alternatives are - to isolate colonies for hemolytic test.

REASON-  The primary inoculating loop is used to streak the plate and stab the agar of the cultured throat swab so that it enables the differentiation of various bacteria upon the characteristic of hemolysis that they eventually produce. and thus the required colonies can be isolated for further hemolytic test to be processed.
