Final answer:
The antibiotic among the options provided that does not have bactericidal action is Tetracycline, which is bacteriostatic as it inhibits protein synthesis.
Step-by-step explanation:
The antibiotics which do not have bactericidal action among the following is: Tetracycline.
The other antibiotics listed, such as Penicillin, Ofloxacin, and Streptomycin are all bactericidal, meaning they kill bacteria.
Tetracycline, on the other hand, is bacteriostatic; it inhibits the growth and multiplication of bacteria by preventing the binding of tRNA to the ribosome, thus hindering protein synthesis, but does not kill the bacteria outright.
