basically, instead of memorizing every small detail when it comes to anatomy q's, just keep in mind basic principles. Since the question said right lobe of the liver, automatically know it can only involve any of the colics (ex ileocolic, right colic, middle colic) EXCEPT the LEFT! From there know that they all drain into the Superior Mesenteric Vein.

Whereas all the left sided structures drain into the Inferior Mesenteric Vein. The spleen is also on the left so you can cross out any answer choice that includes that.

That leaves you with A, the correct answer.

If you need a visual heres a great link. https://radiologykey.com/venous-anatomy-of-the-abdomen-and-pelvis/
