Answer:
C). Could focus on one message and ignore the other one at the same time.
Explanation:
As per the given situation, Colin Cherry's experiment reveals the cognitive process of attention that allows an individual to selectively focus on a distinct stimulus while avoiding or ignoring the other apparent stimulant at the same time. His experiment reveals through 'attention' a person is able to focus one message by designating his/her limited processing ability to that only and ignoring the other perceivable message at the same time in order to concentrate and understand that particular message more effectively. Thus, option C is the correct answer.
