The answer is the third one (C): in vitro; in vivo.

Explanation for each option:

  • In vitro; in loco: This option is incorrect. "In vitro" refers to tests conducted outside of a living organism, such as in a test tube or Petri dish, which is correct for the first blank. However, "in loco" is not the correct term for tests conducted in a living host.

  • In loco; in vivo: This option is incorrect. "In loco" is not a standard term used in this context. "In vivo" is correct for tests conducted in a living host, but the first term is incorrect.

  • In vitro; in vivo: This option is correct. "In vitro" refers to tests conducted outside of a living organism, such as in a test tube or Petri dish. "In vivo" refers to tests conducted within a living organism, such as in a patient.

  • In loco; in vitro: This option is incorrect. "In loco" is not the correct term for tests conducted in a living host, and "in vitro" is correct for tests conducted outside of a living organism, but the order is reversed.

In summary, the correct terms are "in vitro" for tests conducted outside of a living host and "in vivo" for tests conducted within a living host.
