Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A beta-lactam antibiotic is characterized by the presence of a beta-lactam ring in its molecular structure. This class of antibiotics functions by inhibiting the synthesis of bacterial cell walls, leading to the destruction of the bacteria.
Let's analyze each option:
- Vancomycin: This is a glycopeptide antibiotic, not a beta-lactam.
- Amoxicillin: A penicillin-type antibiotic that contains a beta-lactam ring, making it a beta-lactam antibiotic.
- Erythromycin: This is a macrolide antibiotic, which does not contain a beta-lactam ring.
- Doxycycline: A tetracycline antibiotic, also lacking a beta-lactam ring.
Therefore, the correct answer is: Amoxicillin
