Final answer:
The Stroop effect is an example of a controlled process (reading) interfering with an automatic process (color recognition), illustrating how intentional tasks can be disrupted by automatic responses.
Step-by-step explanation:
The example of a controlled process interfering with an automatic process is the b) Stroop effect. The Stroop effect occurs when a person's ability to read the names of colors is interfered with when the color of the text does not match the name of the color (e.g., the word "green" printed in red ink). This effect illustrates how an intentional, controlled process like reading can be disrupted by the automatic process of color recognition, causing a delay in response time or an increase in errors.
