The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis. The epididymis leads to vas deferens.
Or we can say that the vasa efferentia or efferent ducts comiect the rete testis with the initial section of the epididymis.

Mollusca is coelomate. Hemocoel is the body cavity through which blood and coelomic fluid circulate. The blood contains a pigment known as haemocyanin. It helps to carry the oxygen throughout the body. They are suspended directly in the body fluid known as haemolymph. It appears blue. Oxygenation causes a color change between the colorless Cu(I) deoxygenated form and the blue Cu(II) oxygenated form.
So, the correct answer is option C

Haemocyanin in Molluscan Blood
Haemocyanin is a copper-containing protein that is responsible for transporting oxygen in the blood of mollusks. This protein is found in the hemolymph of mollusks such as snails, clams, and octopuses.
Function of Haemocyanin
Haemocyanin is able to bind oxygen due to its copper atoms, and it changes color depending on whether it is carrying oxygen or not. When oxygenated, haemocyanin is blue, and when deoxygenated, it turns colorless.
Comparison to Haemoglobin
Unlike vertebrates, mollusks do not have haemoglobin in their blood. Haemocyanin serves a similar function to haemoglobin by transporting oxygen throughout the body, but it does so using copper instead of iron.
Presence in Molluscan Blood
Molluscan blood contains haemocyanin as its oxygen-carrying pigment. This protein plays a crucial role in facilitating oxygen transport in the hemolymph of mollusks.
In conclusion, haemocyanin is the main oxygen-carrying pigment in molluscan blood, and it serves a similar function to haemoglobin in vertebrates.
