This valve opens to allow blood to flow to the lungs
A
bicuspid valve
B
tricuspid valve
C
aortic semilunar valve
D
pulmonary semilunar valve
Explanation: 

Detailed explanation-1: -The pulmonary valve opens at the systolic phase of the cardiac cycle enabling the deoxygenated blood to be pumped from the right ventricle to the pulmonary circulation. It closes at the diastolic phase of the cardiac cycle, allowing sufficient filling of the right ventricle.

Detailed explanation-2: -Semilunar valves are the passageways between your heart’s ventricles (lower chambers) and arteries. Pulmonic valve is another name for your pulmonary valve. You may see that term when reading about the anatomy of your heart and lungs.

Detailed explanation-3: -The semilunar valves are located at the connections between the pulmonary artery and the right ventricle, and the aorta and the left ventricle. These valves allow blood to be pumped forward into the arteries, but prevent backflow of blood from the arteries into the ventricles.
