Final answer:
The true statement about listening apprehension is that c)it may increase when there is worry about misinterpreting a message, as apprehension stems from anxiety about understanding spoken communication correctly.
Step-by-step explanation:
Listening apprehension refers to a feeling of unease or anxiety that one might experience while trying to understand spoken messages. When considering which of the statements provided is true of listening apprehension, it seems to me that the correct answer is c. it may increase when one worries about misinterpreting a message. This is because listening apprehension often arises from the fear of not properly grasping the content or the implications of what is being said, especially in situations where the stakes of misinterpretation are high.
On the contrary, the option a. 'it is negatively correlated with the complexity of a message,' could be misleading because increased complexity tends to heighten apprehension. Similarly, option b. 'it is reduced when a message is ambiguous or difficult,' seems contrary, as ambiguity generally increases apprehension. Lastly, option d. 'it helps one in attentively focusing on a message,' does not accurately represent listening apprehension, as anxious feelings can actually hinder one's ability to focus.
