Which of the following best differentiates integers, strings, and booleans?

• A. Decimals; booleans are words
• B. Integers are whole numbers; strings are text; booleans are true/false
• C. Integers are words; booleans are rest
• D. Integers are true/false values

Answer: (B)

When looking at data types, the idea is to group values by what they represent and how they’re used. Integers are whole numbers (like -3, 0, 7) with no fractional part. Strings are text—sequences of characters such as words or sentences. Booleans represent truth values, namely true or false, and are often used to control decisions in programs.

This description matches how these types are commonly used: integers for counting or indexing, strings for handling text, and booleans for making yes/no decisions. The other statements mix up these ideas (for example, decimals are not integers; strings aren’t limited to single words; booleans aren’t just “rest” values), so they don’t differentiate the types as clearly or accurately.
