Your vehicle should be inspected by a trained professional at least a. once a year b. twice a year c. once a month d. once every two years

The answer is A. You should believe me. 100 percent sure.

Option (A) is the correct answer.

Explanation:

Your vehicle should be inspected by a trained trained professional once a year because usually every machine needs to be repaired once a year as then there might be dust any disturbance can be caused in its working.

But when we keep on using our vehicle for long and does not let it inspected by a trained person then there might be the development of some serious fault in the  machine which might lead to sever accident or misshapen.

Thus, we can conclude that your vehicle should be inspected by a trained professional at least once a year.
