Final answer:
A. True
True, the use of oral contraceptives increases the risk of stroke (CVA) due to potential blood clots, with combined pills containing estrogen and progesterone having an associated increase in risk.
Step-by-step explanation:
The use of oral contraceptives does indeed increase the risk of cerebrovascular accidents (CVAs), otherwise known as strokes, making the statement true. This heightened risk is due to the potential for blood clots to form as a side effect of taking the pills; clots can lead to blockage of blood vessels in the brain which can cause a stroke. Additionally, the combined pill, containing both estrogen and progesterone, is associated with a slight increase in the risk of blood clots, though it also reduces the risk of ovarian and endometrial cancers. It is important to note that the risk varies depending on the type of oral contraceptive and individual health factors.
