A variable should hold a person's height in meters. Which data type should the variable be?

The variable representing a person's height in meters should indeed be of the float data type. This is because height is typically a measurement that can include decimal values. For instance, a person's height might be 1.75 meters, which requires the ability to store fractional numbers.

Using a float allows the variable to cover a wide range of values, including both whole numbers and those with decimal precision, making it suitable for accurately representing measurements like height.

In contrast, if the variable were an integer, it would be limited to whole numbers only, which would not accurately reflect a person's height if it includes any decimals. A string data type would treat the height as text rather than a numeric value, making arithmetic operations irrelevant. Lastly, a boolean data type only represents true or false values, which is not appropriate for numerical measurements such as height. Thus, float is the most suitable choice for this scenario.
