The viscosity of lubrication oil is described by a number. A low viscosity number describes oil that:

Explanation:
Viscosity is a measure of how easily a fluid flows—the resistance to flow. A low viscosity number means the oil is thin and flows readily, so it moves through the system and reaches surfaces quickly with little resistance. That’s why the best choice describes it as flowing easily. The other ideas describe properties not tied to flow behavior: resisting flow would correspond to a thicker oil, hardening at high temperature isn’t a direct measure of viscosity, and absorbing moisture relates to hygroscopic properties rather than flow.
