Answer:
A. Instructions for changing the oil filter on a car.
Step-by-step explanation:
A visual aid is an instructional device that appeals to the vision. This is a good way to help to understand or remember better than textual aids.
From the options given the one that would be more helpful is the A because you have to perform an action. With images, it should be better to understand how to change the oil filter rather than only with text. If you only have information to read in this case, you need to have prior knowledge about the parts of a car.
I hope this answer helps you.
