What data types can be stored in an array?

The answer is correct because an array is a versatile data structure that can hold multiple values of the same type or, in some programming languages, different types of data. Specifically, in many programming environments, an array can store various data types, such as strings, integers, doubles, and booleans.

This functionality allows for efficient collection and manipulation of data, especially when a program needs to handle lists of multiple items of different types together. For example, an array can include a sequence of temperature readings stored as doubles, user age stored as integers, names of users stored as strings, and flags stored as booleans representing conditions or states.

In contrast, the other options are limited in scope, focusing on fewer data types or specific categories that do not represent the full capability of arrays in most programming contexts. This limitation prevents leveraging the flexibility arrays can provide when working with complex data management tasks in programming.
