Answer: B

Explanation:

A string is the data type that a developer should use when creating a variable to hold a postal code. A string is a sequence of characters that can represent text, symbols, or numbers. A string can store any value that can be typed on a keyboard, such as “Hello”, “123”, or “90210”. A string is enclosed by quotation marks to distinguish it from other types of data. A postal code is an example of a value that can be stored as a string.
