Final answer:
The best data type for storing a person's height in meters would be a float because it allows for continuous numeric values that can have decimals, which are essential for precise measurement.
Step-by-step explanation:
The best data type for a variable to store a person's height in meters would be Float.
A Float data type is used to represent decimal numbers, which can accurately store a person's height in meters. For example, a person's height might be 1.75 meters or 1.85 meters. Integer data types can only store whole numbers, while String data types are used for textual information and Boolean data types are used for true/false values.
To store a person's height in meters, the best data type would be a float. This is because a person's height is a continuous measurement and can have decimal values, which are represented accurately with a float data type. An integer would not be suitable as it only allows for whole numbers, without decimal places. A string is not ideal as it would treat the height as text rather than a numeric value that can be calculated with. Likewise, a boolean is not appropriate since it is only used to represent true or false values. Therefore, to answer the question: Which of the following would be the best data type for a variable to store a person's height in meters?, the choices being 1) String, 2) Integer, 3) Float, 4) Boolean, the correct answer is option 3, Float.
