C) Read the following abstract and answer the following question:

Abstract: The objective of this study was to observe the inhibitory effect of garlic (Allium sativum) against various bacterial strains The aqueous extract of garlic was tested against Escherichia coll Staphylbenicus aureus and Salmonella typhi in results, we found that in the agar cup diffusion method, the aqueous extract gave the same inhibition zone towards E cel and 5. typhi, but no Inhibition zone was observed for S. aureus. The overall result shows that the aqueous extract was most powerful against the pathogenic gram-negative bacteria. This result gives us confidence that the conventional medicinal approach can be used for treating several elements.
