Choose the most appropriate conjunction to fill in the blank in the following sentence. ___ or not my mother permits, I am going to the movie hall.

Correct option is B

The correct option is (b) Whether.

Explanation:
The sentence expresses a situation where the speaker intends to go to the movie hall regardless of the mother's permission. The conjunction whether is used in the structure whether or not, which means regardless of whether a condition is true or false.

Correct answer – Whether:
The structure whether or not is used to indicate that both possibilities (permission given or not given) lead to the same outcome.
(Hindi meaning: चाहे ... हो या न हो)
Example: Whether or not it rains, the match will be played.

Explanation of Other Options:

• (a) Until – Used to indicate a time limit (जब तक); e.g., Wait until she arrives. Does not fit the ___ or not structure.
• (c) If – Used for conditional sentences; if or not is not a standard grammatical structure in English.
• (d) Unless – Means except if; unless or not is grammatically incorrect and meaningless.
