Which item is used to aid the visual inspection for leaks?

Explanation:
Soap solution is used to reveal leaks because applying a soapy mixture to joints, hoses, and connections makes escaping gas form bubbles. Those bubbles appear right at the leak site, making even very small leaks visible during the visual inspection. Spare parts or a wrench are for maintenance and do not help identify leaks, while a flashlight and mirror aid visibility but don’t indicate leaks by themselves.
