What types of data can be stored in MongoDB?

MongoDB is designed to handle a wide variety of data types, which is one of its key advantages as a NoSQL document-oriented database. The correct answer recognizes that MongoDB can store data as strings, integers, arrays, dates, and embedded documents.

Strings and integers are basic types for representing text and numeric data, respectively. Arrays allow for storing lists of values within a single document, enabling the representation of more complex data structures. Dates are essential for managing temporal information. Embedded documents allow for nesting documents within documents, providing an efficient way to store related data together and maintain hierarchical relationships. This flexibility is crucial for applications that require dynamic data modeling, as it allows developers to accommodate various data structures without predefined schemas.

The other options are too restrictive or misrepresent the capabilities of MongoDB. For instance, only being able to store text and numbers greatly underestimates the flexibility MongoDB offers. Limiting storage to just photos and videos would ignore the wide range of data types MongoDB can manage, and insisting on structured data in fixed schemas contradicts the database's schema flexibility, which is one of its main benefits.
