    Second

    Explanation:

    All the options from A through to D are correct units of time but in science, by agreement, the SI unit for time that is used is the second. Which is why speed is presented in meters per second, and acceleration in meters per second squared as just two examples. It is a more useful unit for measurements done in a science lab compared to a minute, hour or even worse a day.
