Answer: D) precapillary sphincters relax.
Explanation:
Blood flow to a tissue will decrease if precapillary sphincters relax as, capillaries provides glucose and oxygen to the cells and allows blood to flow through it when the muscle ring known as the precapillary Sphincters get relaxed. The blood flow is stopped when the precapillary sphincters constrict flow of blood. As, certain chemical signals causes feeder arterioles to dilate and bring more blood into local areas then, it causes precapillary sphincters to relax.

Cancer occurs when a few of the body's cells grow out of control and spread to other internal organs. The trillions of cells that make up the human body are home to cancer, which can develop practically anywhere. Cancers are any of the many diseases that are characterized by the expansion of abnormal cells that divide uncontrollably, have the ability to penetrate, and cause harm to good physiological tissue.
Cancer cells acquire gene alterations that transform them from healthy cells to cancer cells. These gene mutations can be passed down via families, develop gradually as we age and our genes deteriorate, or show up if we are exposed to chemicals that damage our genes, such as alcohol, tobacco smoke, or ultraviolet (UV) radiation from the sun.
