Q.

. Example of discrete variable

\newline

A. Masses in

\mathrm{kg}

of sticks patients in an hospital

\newline

B. The production capacity of an industrial machine

\newline

C. Measuring the litres of palm oil in a drum

\newline

D. The number of new babies in a maternity ward

Understand discrete variables: Step $1$ : Understand the concept of discrete variables. Discrete variables are countable in a finite amount of time. Examples include the number of students in a class, the number of cars in a parking lot, etc.
Analyze options: Step $2$ : Analyze each option: $\newline$ A. Masses in kg of sticks patients in an hospital - This is a continuous variable because mass can be measured in infinitely divisible units. $\newline$ B. The production capacity of an industrial machine - This is typically a continuous variable, as capacity can vary and be measured in continuous units. $\newline$ C. Measuring the litres of palm oil in a drum - This is a continuous variable because litres can be measured in infinitely divisible units. $\newline$ D. The number of new babies in a maternity ward - This is a discrete variable because you can count the number of babies; they are distinct and separate units.
Identify correct answer: Step $3$ : Identify the correct answer based on the analysis. Option $D$ is the only example of a discrete variable.
