Which of the following valve cores are recommended for use in TPMS sensors? a. Unplated brass caps b. Brass valve cores c. Nickel-plated valve cores d. Aluminum valve cores

The correct answer is c. Nickel-plated valve cores.<br /><br />Explanation: Nickel-plated valve cores are recommended for use in TPMS (Tire Pressure Monitoring System) sensors because they provide better corrosion resistance and durability compared to other materials. This ensures the longevity and reliability of the TPMS components.
