The question is clearly flawed by asking for lymphocyte production at low stress levels twice. However, based on what is known about the effects of norepinephrine on the immune system, it can be assumed that at low stress levels, norepinephrine increases lymphocyte production. However, at high stress levels, norepinephrine has been shown to decrease lymphocyte production due to its suppressive effect on the immune system. Therefore, option B, which states that norepinephrine increases lymphocyte production at low stress levels but decreases it at high stress levels, is the most likely correct answer.

The Production of Norepinephrine Causes _____ in Lymphocyte Production at Low
