nexus9112 [7]

The question is incomplete as it does not have the options which are:

resistant

semisynthetic

synthetic

natural

Answer:

Semisynthetic

Explanation:

Antibiotics are the microbial compounds which are obtained from the micro-organisms which are found effective against the bacteria as they act by inhibiting the activity of the bacteria which ultimately kills the bacteria.

These antibiotics can also be distinguished based on their synthesis: natural, semi-synthetic and synthetic antibiotics.

The semi-synthetic antibiotics are the antibiotics which are obtained from the microbes but are modified artificially by making chemical changes to increase the effectiveness of the antibiotic and making the antibiotic as broad-spectrum bacteria.

Since the properties of the antibiotics provided in the question are similar to the semi-synthetic antibiotics, therefore, is considered semi-synthetic bacteria.

Thus, Semisynthetic  is correct.
