B) Urine output will increase.
C) Systemic blood pressure will go up.
D) Glomerular filtration rate will increase.

Vasodilation of the afferent arteriole will decrease resistance to blood flow into the glomerulus, which normally results in an increased filtration rate and urine output. The net filtration pressure in the glomerulus will also increase. However, systemic blood pressure is unlikely to increase because the vasodilation of the afferent arteriole will reduce the resistance to blood flow, which may help to decrease systemic blood pressure rather than raise it.
