To beg the question

The correct answer is B: To take for granted.

Here's why:
The idiom "to beg the question" doesn't mean "to ask a question".
It actually means to assume something is true without providing evidence for it.
Think of it as assuming the very thing you're trying to prove, like a circular argument.

Let's look at the other options:
A: To refer to - This doesn't relate to the meaning of the idiom.
C: To raise objections - While begging the question can lead to objections, it's not the definition itself.
D: To be discussed - Something "to be discussed" isn't necessarily related to assuming something without proof.
E: None of these - Is incorrect because B is the correct answer.

Therefore, the best fit is "To take for granted" because it accurately describes the action of assuming something to be true without proper justification.
