Lauryn Fitzpatrick · Answer 1

Option A

Explanation:

Any mild acidic substance such as vinegar etc. can be used for removing rust from metal. White vinegar is commonly used and is applied on the rusty regions of any metal substance. After couple of hours, when the reaction between rust and vinegar is complete, the rust dissolves in vinegar completely. The metal surface can be cleaned just by wiping the surface of the object

Hence, option A is correct
