Final answer:

b) Cephalosporins

c) Bacitracin

Cephalosporins and Bacitracin inhibit bacterial cell wall synthesis, while Tetracycline inhibits protein synthesis, and Ethambutol targets mycobacterial cell walls.

Step-by-step explanation:

The antibiotics that inhibit bacterial cell wall synthesis are b) Cephalosporins and c) Bacitracin. These antibiotics interfere with the synthesis of peptidoglycan, which is a vital component of the bacterial cell wall, leading to osmotic lysis and cell death. In contrast, a) Tetracycline does not inhibit cell wall synthesis; instead, it is known for inhibiting bacterial protein synthesis by blocking the attachment of the tRNA-amino acid complex to the ribosome, particularly the A site, thus interfering with the codon-anticodon interaction during the translation process. d) Ethambutol is an antimicrobial used to treat tuberculosis, and it inhibits the synthesis of the cell wall in mycobacteria, not typical bacterial cells.
