Solution

The correct option is A Translation
Tetracycline binds to 30S subunit of the ribosome in prokaryotes. It prevents attachment of aminoacyl t- RNA to the ribosome-mRNA complex during the translation process thereby inhibiting it. Thus, protein formation is halted.
Hence 'translation' is the correct option.
