Answer:
see thats because stress is a feeling and feelings are mostly connected to hormones so when you are stressed or feel threatened, your nervous system responds by releasing a flood of stress hormones, including adrenaline and cortisol, which rouse the body for emergency action. Your heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and your senses become sharper.
The first option would be correct. RAISED HEART RATE AND SPED-UP NERVOUS SYSTEM.
