The correct options is capillaries

Small blood arteries called resistance vessels, like arterioles, control blood flow and are essential in managing vascular resistance. On the other hand, blood vessels with a large ability to store blood are referred to as capacitance vessels. They serve as reservoirs that may change in size to hold various amounts of blood.

One of the choices offered is:

Arterioles and capillaries are linked by small arteries called metarterioles. They restrict blood flow into capillary beds by acting as transitional areas between arterioles and capillaries. Metarterioles aren't frequently referred to as capacitance vessels, though.
Small veins called venules are responsible for transporting blood from capillaries to larger veins. Even though venules have a limited capacity for expansion, their main function is blood collection rather than serving as substantial capacitance conduits.
Veins: Veins are blood vessels that return anaemic blood from various bodily tissues to the heart. Compared to arteries and arterioles, veins have a higher capacitance because their walls are more flexible and have a bigger luminal diameter. They serve as capacitance vessels in the circulatory system and can expand to hold a lot of blood.
The smallest blood vessels, called capillaries, are where waste products, nutrients, and oxygen are exchanged between the blood and tissues nearby. Although they are essential for enabling exchange, capillaries are not commonly regarded as capacitance channels. They don't have a lot of storage and have flimsy walls.

Because veins can hold more blood and serve as a reservoir for the cardiovascular system, they are the most suitable alternative among the options given for capacitance vessels.
