Answer:

The most likely hormone released to Gina and her body deal with this dangerous and frightening situation is the adrenaline or epinephrine.

Explanation:

Adrenaline, also called epinephrine, is a neurotransmitter secreted to the bloodstream by the adrenal gland. Under pressure or stress, it is considered to be a survival hormone, as it triggers physiological changes in the body necessary to be fast or strong.

Adrenaline increases heart beating, blood pressure, stimulates breathing and dilation of the respiratory tract.  It also increases glucose concentration in blood. It is responsible for the attack, defend or escape reactions.
