Answer 1

The correct option is A The flow of blood to tissues beyond the clot will be reduced

A clot may reduce the flow of blood to tissues beyond the clot. Thus reducing the transport of food and oxygen to those tissues. If a clot blocks an artery that nourishes the heart then a heart attack may occur. If a clot blocks an artery to the brain, a stroke may occur.
