Solution
The correct option is B Tetracyclin
A bacteriostatic drug or agent is a biological chemical agent that stops bacteria from reproducing, while not necessarily killing them otherwise. There are some bacteriostatic antibiotics like tetracycline. Tetracycline act by interfering with the ability of a bacterium to produce certain vital proteins, thus, they are inhibitors of growth (bacteriostatic) rather than killers (bactericidal).
Penicillin is bactericidal, prevent cross-linking of peptidoglycan, causing cell lysis.
Streptomycin is bactericidal as it causes membrane permeabilization caused by insertion of mistranslated proteins into cytoplasmic membrane.
Ciprofloxacin is bactericidal that inhibits the enzyme DNA gyrase, required for replication of DNA.
Thus, the correct answer is the option (B), 'Tetracycline'.
