Why are primitive data types useful to programmers?

They allow more control because programmers can specify how to manipulate a primitive data type and where to store it$.$

They save time because programmers only tell the programming language what to do with the primitive data type, not how to do it$.$

They are the simplest variable type available and do not require any functions to manipulate the associated data.

They are not built into your programming language but can be constructed as desired from composite data types.
