if you keep only One choice of option probability of getting that right is higher that probability of random choice of option

How's that?

see i will try to explain by an example here... 50 options and you kept all the options as A. so the changes of A increases significantly when compare to selecting options at random. [of course the debate lies on sheer luck too] but probability wise selecting one option can yield you better result.

I don't think that's how statistics works. Assuming the distribution is random, each answer has a 1:4 probability of being correct, regardless of what you choose.

It's like flipping a coin. Choosing "tails" every time doesn't give you an edge over picking at random.

That's true but here the distribution on right answers vary, your case study is absolutely true if A B C D are evenly true answers. since the answer set vary i believe absolute probability also vary. but I do condone with the theoretical info. This practice is with experience of attempting various such exams with no negative marks. but again... this approach is not true probability rather experienced... I mean what else to say 😛😛
