In the 1950s John Garcia and His Colleagues Wondered Whether

In the 1950s John Garcia and his colleagues wondered whether the rats had developed a taste aversion for the food and water they had consumed while they received radiation. Which of the following statements is true as per this research conducted by John Garcia?

A) An organism could not be conditioned to avoid a taste they previously liked, by alternating between an unconditioned stimulus and conditioned stimulus.
B) Conditioning can happen only if an organism is exposed repeatedly within a brief time span (a few seconds) to the unconditioned stimulus (UCS) and conditioned stimulus (CS) together.
C) An organism cannot be conditioned to respond to just any "neutral" stimulus paired with an unconditioned stimulus.
D) Reflexive responses (such as nausea) could be conditioned to any kind of stimulus, as taste aversion is not depended on stimuli.
