Satish,

I would go with meaning of the sentence to differentiate between the 2 options. C is just more logical.

To give an example:

1. Doctors mistook Tom's common cold for final stage of blood cancer and informed Tom that there was no medical cure for his condition.

or.

2. Doctors mistook Tom's final stage of blood cancer for the common cold and informed Tom that there was no medical cure for his condition.

Obviously, option 2 is illogical.

Coming back to our question. The sentence actually gives you a subtle hint regarding the answer by adding the adjective "simple" before menstrual cramps. So I would just look out for such a hint regarding such questions.

Hope this helps.

Option 2 is logical to me. In the original problem, Option 'B' is close to Option-2 in your example. This makes sense to me.

Mistook X for Y:
In simple terms: Mistook it as X. But it is infact Y. Is it correct? WHats your interpretation of Mistake A for B; Exchange A for B in simple terms?

I agree with you in your example. Option 2 is logical to me. In the original problem, Option 'B' is close to Option-2 in your example. What do you think?

Mistook X for Y:
In simple terms: Mistook it as X. But it is infact Y. Is it correct?
Yes Correct. Just look out for hints in the sentence itself. Normally you will not have to guess which is the worse ailment/ the thing of higher degree.

The reason it should be C is due to the usage of word Simple.

Logically, if you think then 'Simple' itself means that it is easy to cure.

How can something that is easy to cure be called incurable?
