If an outdoor runner develops a headache, feels tired, and has an elevated heart rate, the most probable cause is Dehydration. The answer is letter B. Because while exercising, you are sweating a lot and your body excretes water. The more you excretes water, the more dehydrated you become and so you need water to replenish dehydration.

if your boyfriend is cheating on you, my best advice to you is to dump him, he's only going to drag you down. and if you do, don't fret there's plenty better that know how to treat a person right. i mean honestly, the whole point of a romantic relationship is love, and if you love someone you aren't going to cheat on them. i do believe in second chances, but why would he cheat in the first place? i personally feel that if someone cheats, they ruin any chance they wanted/had with you. i wish you the best of luck with this, hang in there.
