(A) Morphine
(B) Penicillin
(C) Streptomycin
(D) Chloramphenicol

Answer 1

Hint: An antibiotic is a medicine that helps stop infections caused by bacteria. Antibiotics when applied on the surface, kills the bacteria, stopping their copying and reproducing.
In short, the drug that kills the germs in our body is known as an antibiotic (name means against life).

Complete answer:
Let us have a basic idea about the antibiotics-
Antibiotics-
They are also known as antibacterials which are the medications to destroy or slow down the growth of bacteria in a media. These do not treat viral infections such as flu, cold, etc.
They only treat bacterial disorders such as strep throat, urinary tract infections and E. coli. These drugs can be taken by mouth or can be injected as well. Some of the creams, lotions and ointments are also anti-microbial or antibiotics. They have some side effects too such as rash, nausea and diarrhoea.
Antibiotics are generally grouped together based on the work they perform. Each type of bacteria only works against certain types of bacteria or parasites and would be helpless for other types of bacterias.
The common antibiotics from the given illustration are Penicillin, Streptomycin and Chloramphenicol. Whereas, Morphine is an analgesic drug to relieve severe pain.

Therefore, option (A) is correct.

Note:
Antibiotics are also used to treat or prevent protozoan’s infections along with bacterial infections. These drugs are usually taken through mouth but in severe cases, these can be injected as well. The allergies can be caused by the intake of the antibiotic which can be considered as the side-effect of the same.
