Explanation:

The minimum bactericidal concentration (MBC) test determines the lowest concentration of an antimicrobial agent that kills microbes (bactericidal effect). "Growth enhanced" is incorrect as antimicrobials don't enhance growth. "Growth inhibited" refers to minimum inhibitory concentration (MIC), not MBC. So the correct option is about microbes being killed.

Answer:

the microbes were killed
