I think D is the answer, but I'm just going to guess. This psychology stuff is like a foreign language to me.

Hmm, I'm a bit confused. Isn't the matching law about rats running on wheels for cheese? How does that apply to this question?

I'm going with C. The organism will respond exclusively to the alternative with the highest rate of reinforcement.

I'm pretty sure B is the right answer. The proportion of responses will become equal over time, even if the reinforcement rates are different.

Option D looks like the correct answer to me. The matching law states that the proportion of responses will match the proportion of reinforcers obtained.

That makes sense. It's important for behavior to be influenced by the rate of reinforcement. Option D seems to capture that idea.
