Hindus practise idolatry,
Options-
a)- don't they?
b)- haven't they?
I think the answer is "don't they" but, according to the question the answer is "haven't they"
Why??? Please someone explain it to me...

Tag questions are used to confirm or check information or yet to ask for agreement.
And it's formed by an affirmation followed of a question made by the negation of its auxiliar verb
This way, since your question is in the present, option a
is the right complement.
Hindus (do) practice idolatry, don't they?
You just could finish it with haven't they?
if you make the question in the present perfect:
Hindus have practiced idolatry, haven't they?
Similarly you could, for example, ask tag questions in the negative form. But whatever time tense you choose use, the auxiliar verb in question part need to agree with the one used in the affirmation part:
Hindus didn't practice idolatry, did they?
The question has gotten it wrong. A
is the correct answer. If the question said Hindus have practised idolatry,
then the correct answer would be B
.
The rule is that the tag question has to agree in tense with the main sentence and therefore use the auxiliary verb that the main sentence uses. If there is no auxiliary verb, then use the form of do that agrees in tense. Except use have or be if one of those is also the main verb in the sentence.
Some examples?
I go walking every morning, don't I?
I really messed that up, didn't I?
I have blue eyes, haven't I? ("Don't I?" is probably more typical in American usage.)
It's cold, isn't it?
I have really messed that up, haven't I?
I had gone too far by then, hadn't I?
I would get very wet if I went outside, wouldn't I?
I can make biscuits tomorrow, can't I?
I could do it later, couldn't I?
I should do the dishes after dinner, shouldn't I?
And also, you can do the reverse:
I don't go walking every morning, do I?
I didn't mess that up, did I?
I haven't spent all my money yet, have I?
Children don't like coffee, do they?
I'm not missing anything, am I?
I don't have blue eyes, do I? ("Have I?" is an alternative British usage.)
I haven't blue eyes, have I? (This is an alternative in British usage.)
And so on.
