Which of the following is a unit used to measure time?

Time is measured by how long something lasts, and the base unit used for this in the SI system is the second. A second expresses duration, so this is the unit you’d use to say how long an event takes. The other options measure different things: the meter is a unit of length, the kilogram is a unit of mass, and the candela is a unit of luminous intensity.
