B. A worn belt tensioner
Explicación
## Step 1The problem presents a situation where an air conditioning (A/C) drive belt makes a chirping noise only when the A/C is on. The task is to identify the most likely cause of this noise from the given options.## Step 2Let's analyze each option:### A. An open A/C clutch diodeThe A/C clutch diode is responsible for controlling the electrical current to the clutch. If it's open, it could cause electrical issues, but it's not directly related to the belt's chirping noise.### B. A worn belt tensionerThe belt tensioner is responsible for maintaining the tension of the belt. If it's worn, it could cause the belt to slip, which could lead to a chirping noise.### C. A low refrigerant chargeA low refrigerant charge could cause the A/C system to work harder, which could lead to various issues. However, it's not directly related to the belt's chirping noise.### D. An incorrect refrigerant typeUsing the wrong type of refrigerant could cause the A/C system to work inefficiently, but it's not directly related to the belt's chirping noise.## Step 3Based on the analysis, the most likely cause of the chirping noise is a worn belt tensioner. This is because the tensioner is directly related to the belt's operation and its wear could lead to the belt slipping, which would cause a chirping noise.
