Refer to the scenario below to answer the questions that follow.
In an extended experiment, rats receive five kinds of trials within four-hour-long sessions of daily training over a period of five months. A tone is followed by food only when it is preceded by a small light on the left side of the wall (L_L) ; no food is given when the tone is presented by itself (L_L→T+, T‒) . A small light on the right side of the wall (R_L) is followed by food when it was preceded by a clicker; no food is given when the tone is presented by itself (C→R_L+, R_L‒) . Finally, a white noise (N) is followed by food 40% of the time.
-If L_L is an occasion setter, the rats will respond

A) to the presence of L_L by rearing only when T is present.
B) with head jerking when T is preceded by L_L.
C) with rearing and head jerking during T when it is preceded by L_L.
D) as much to L_L→T as to T.
