Stress has been shown to put people at a higher risk for________.

A) unplanned pregnancy
B) heart attack and stroke
C) promotions at work
D) schizophrenia

Stress has been linked to an increased risk for heart attack and stroke, as it can narrow blood vessels and increase blood pressure. There is no evidence to suggest that stress has an impact on unplanned pregnancy or promotions at work, and while stress can worsen symptoms of schizophrenia, it is not a risk factor for developing the condition.
