Question

why is the main reason to move the person in need of help to a dry area when using an aed?
water might ground the aed.
water can interfere with the aeds reading.
electricity can travel through water.
electricity will not flow through a wet body.

Explanation:

When using an AED, the main concern is that electricity can travel through water. If the person is in water or a wet - area, the electrical shock from the AED could potentially harm rescuers or others nearby through the conductive properties of water. Water grounding the AED is not the main reason. Water doesn't directly interfere with the AED's reading in a way that is the primary concern. And electricity does flow through a wet body.

Answer:

C. Electricity can travel through water.
