A measurement based on properties of time, like minutes of a radio conversation is identified as

Correct option is D

A durational unit is a measure used to represent the length or duration of an event in terms of time. For example, minutes in a radio conversation measure how long the conversation lasts. These units are commonly used in fields like communication, time management, and performance evaluation to quantify and compare time-related events. A durational unit emphasizes the extent or amount of time taken by an activity, distinguishing it from other time-related measures.
Information Booster 1. Durational units quantify the length of time of an activity, such as seconds, minutes, hours, etc.
2. They are used in both qualitative and quantitative research to structure time-based data.
3. In media studies, durational units help evaluate content length, such as program duration.
4. These units are also essential in workflow analysis and time-motion studies.
5. Unlike a temporal unit, which may refer to segments or frames of time (like intervals), a durational unit focuses purely on the elapsed time of a continuous activity.
