Verified step by step guidance

Begin by identifying the function of each hormone listed in the options. Epinephrine is primarily involved in the 'fight or flight' response, increasing heart rate and energy availability.

Understand the role of cortisol, which is a glucocorticoid that helps regulate metabolism and the body's response to stress, but is not directly involved in maintaining blood pressure and blood volume.

Consider insulin, which is a hormone that regulates blood glucose levels, not directly related to blood pressure or blood volume.

Focus on aldosterone, which is a mineralocorticoid produced by the adrenal cortex. Its primary function is to regulate sodium and potassium levels, which in turn helps maintain blood pressure and blood volume.

Conclude that aldosterone is the hormone responsible for maintaining blood pressure and blood volume by promoting sodium retention in the kidneys, which leads to water retention and increased blood volume.
