When examining a car which of the following should be checked for possible fluid leaks? Rev the engine when parked Walk around the car Test-drive the car Look under the car

## Step 1<br />The question is asking about the best method to check for possible fluid leaks in a car. The options provided are: revving the engine when parked, walking around the car, test-driving the car, and looking under the car.<br /><br />## Step 2<br />Revving the engine when parked (option A) is not a practical method to check for fluid leaks. This is because the engine is not running, and therefore, no fluid will be flowing through the engine.<br /><br />## Step 3<br />Walking around the car (option B) can help identify any visible fluid leaks, but it is not the most effective method. This is because some fluid leaks may not be visible from the outside.<br /><br />## Step 4<br />Test-driving the car (option C) can also help identify fluid leaks, but it is not the most effective method. This is because some fluid leaks may not be visible during the test drive.<br /><br />## Step 5<br />Looking under the car (option D) is the most effective method to check for fluid leaks. This is because it allows you to see any fluid that may be dripping from the engine or other parts of the car.
