Could 'although' possibly make do?

[Zishuli]

This is a question in test# TOEIC/ W298:

5. conj. if

(a) whereas
(b) whether
(c) although
(d) except

The given answer is (b)' whether'. I wonder if (c)' although' could possibly be accepted.

I have looked up the dictionary and got an explanation of the conj. ' if ' as below:

2. Although possibly; even though: It is a handsome if useless trinket.

'If' connotes a condition or logic whereas 'although' questions the logic :)

if is 'conditional'
although is 'explanatory'

I may pass the exam IF I study-

I did not pass the exam, ALTHOUGH I studied-

does this help? :P

I hear you Esl_Expert.
In this case, the issue is if whether I agree with you when replying to the specific answer questioned.

You say: 'The word ¨if¨has a several possible.......
Dare I say the a does not belong in that sentence?
