The data type used to represent text, consisting of a collection of characters, is the string. Strings are specifically designed to handle sequences of characters, making them ideal for storing words, sentences, or any text-based information. Additionally, each character in a string can be accessed individually, allowing for operations such as slicing, concatenation, and character replacement.

Arrays and lists can contain various data types, including strings, but they themselves are not specifically designed to handle text. They are collections that can store multiple elements and are not limited to character data. Objects are more complex structures that can contain various data types and methods, making them suitable for more complex data modeling but not solely focused on text representation. Therefore, the string is the most appropriate choice for representing a collection of characters.
