(a) Because it is a Broad spectrum antibiotic

(b) Because it is a Narrow spectrum antibiotic

I had been asked this question in an interview for job.

My question is taken from The Story of Penicillin:How Biologists and Engineers Work Together in division Bioprocess Development of Bioprocess Engineering

Answer 1

Correct choice is (b) Because it is a Narrow spectrum antibiotic

To elaborate: Penicillin is the Narrow spectrum antibiotic that only kills the specific bacteria or microorganisms and not the normal bacteria or microorganisms present in Human body, in this way human body is unaffected.
