Which of the following is a type of data the computer can handle?

The correct answer encompasses a broader concept than the selected option suggests. A computer can indeed handle various types of data, which includes strings, characters, and graphs.

Strings are sequences of characters used to represent text, while characters themselves are the individual elements that form strings (like letters, numbers, or symbols). Graphs can represent data visually, often used to illustrate relationships or structures, such as connections between different data points.

By recognizing that each of these data types serves a specific purpose and can be manipulated and processed by computers, it becomes clear that the encompassing option indicates that all of these types are valid forms of data input that a computer can manage. This versatility allows for a wide range of applications in programming and data management.
