Which of the following data types is used to implement a simple counter application?

A Boolean data type can only represent two states (true/false, 0/1) and is not suitable for counting beyond a binary state.

An integer data type represents whole numbers (positive, negative, or zero) without fractional components, which is ideal for a counter that increments or decrements by whole units.

A string data type is used for sequences of characters (text) and is inefficient and inappropriate for numerical operations like counting.

A floating-point data type represents numbers with fractional parts, which is unnecessary and less efficient for a simple counter that only needs whole numbers.
