The right option is; A. ore

Minerals that are valued because they contain large amounts of a useful element are called ores.

Ores are naturally occurring rock substances that contains large amount of utilitarian materials, usually metals or gems that can be extracted profitably from the deposit. The extraction of the ores from the earth is done through mining and they are processed to remove the valuable elements. Ores are grouped based on their formation and they include; magmatic or volcanic ores (such as iron and copper ores), carbonate alkaline ores (such as diamonds) and metamorphic ores (such as silver, lead and zinc ores).

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

but there is no

i guess you forgot putting it.
