@Alexander-Richards, happy to help!

The passage argues that electronic devices cause risk to modern navigation systems. As you state, (A) shows that electronic devices are the problem. This corresponds nicely with the logic of the passage's argument - electronic devices create problems for navigation systems. In other words, electronic devices are the cause and risk to modern navigation systems is the effect.

(A) shows that when electronic devices disappear, the risk to modern navigation systems also disappears. In other words, it shows that when the cause is eliminated, the effect is also eliminated. This strengthens the argument by adding support for the idea that electronic devices cause risk to modern navigation systems. Since the question is looking for the answer choice that least strengthens the argument, (A) would be incorrect.

Does that make sense? Please let us know if you have any other questions!
