The definition of a chemical that inhibits bacterial growth without harming body cells is indeed best represented by the term "antibiotic." Antibiotics are substances that selectively target bacteria, interfering with their growth or reproduction while generally being safe for human cells. This selectivity is a key feature of antibiotics; they exploit differences in the cellular processes between bacteria and human cells, such as cell wall synthesis and protein production.

Antiseptics, although used to prevent infection, are typically applied to living tissues. They may be more broadly effective against various pathogens, including bacteria and viruses, but their use and potential harm to body cells make them distinct from antibiotics.

Antimicrobials is a broader term encompassing all substances that kill or inhibit the growth of microorganisms, including both antibiotics and antiseptics.

Disinfectants are strong chemicals used to eliminate pathogens on inanimate objects and surfaces and are not safe for use on living tissues.

Overall, antibiotics specifically target bacterial growth while minimizing harm to human cells, making them the most appropriate term among the options given.
