Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Antibiotics are classified as bactericidal or bacteriostatic.
• Bactericidal antibiotics kill bacteria.
• Bacteriostatic antibiotics inhibit bacterial growth.
Step 1: Understand bactericidal antibiotics. Bactericidal antibiotics destroy bacterial cell walls or vital cellular functions leading to bacterial death. Penicillin belongs to this category.
Step 2: Examine other antibiotics. Erythromycin, tetracycline and chloramphenicol generally act by inhibiting protein synthesis and are mainly bacteriostatic.
Step 3: Identify the correct answer. Among the given options, Penicillin is bactericidal. Therefore, \[ \boxed{\text{Option (1)}} \]
