13.) The 10th digit of a 17 digit vehicle identification number (VIN) indicates: CA. country of origin B. manufacturer C. engine type D. year of manufacture.

The correct answer is D. year of manufacture.<br /><br />In a 17-digit vehicle identification number (VIN), the 10th digit indicates the year of manufacture. The VIN is a unique code that identifies a specific vehicle and provides information about its manufacturer, model, and other characteristics. The 10th digit is used to represent the year of manufacture, with the first two digits indicating the year and the second two digits indicating the month of production. For example, a VIN with the 10th digit as '2' would indicate that the vehicle was manufactured in the year 2023.
