A simple Standard definition is normally composed of all of the following except:

Because its not B or D . I don't know what the heck this "class" is?

"Class" in this context is another term (a shortened term?) for "classification."

There's only one of those choices that is vague about what's included ... and it's not C!!

Then A right? Its pretty vague

Yes. You're right now. A is correct.

To determine the correct answer, let's break down each option:

A) Characteristics of some class: A standard definition typically includes the characteristics or qualities associated with a particular class or group.

B) The term to be defined: This is an essential component of a standard definition as it identifies the specific word or concept being defined.

C) A class containing the term to be defined: This option suggests that a standard definition includes a class or category that encompasses the term being defined. While this may be relevant in some cases, it is not a fundamental requirement for a simple standard definition.

D) The distinctive characteristics of the term: This component is often included in a standard definition to highlight the unique or distinguishing features of the term.

Considering the options, it is evident that option C does not align with the essential elements of a standard definition. Therefore, the correct answer is C.
