Which of the following scenarios is best represented by a Boolean data type?
A light switch being either on or off.
The number of pages in a book.
The price of an item in a store.
A user's full name.
A Boolean data type represents a value that can only be in one of two states, typically true or false. A light switch being either 'on' or 'off' is a perfect real-world example of a binary state, making the Boolean data type the most suitable choice for its representation. The price of an item would be a float (a number with a decimal), a user's name would be a string (a sequence of characters), and the number of pages in a book would be an integer (a whole number).
