The correct option is A Take
The zero conditional is used for when the time being referred to is now or always and the situation is real and possible. The zero conditional is often used to refer to general truths. The tense in both parts of the sentence is the simple present. In zero conditional sentences with a negative connotation, the word "unless" is used. Hence, Option A is correct. The rest of the options do not adhere to this rule, hence incorrect.
