A. Rohypnol (also known as Roofies)
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.
