Hello! I'm sorry for being so lazy. I know the best way to learn is thinking carefully before asking. I know I should have my oppinion first and then you'll give yours to explain whether I'm right or wrong. I've got it.
Well, I think the answer for this is B. But I'm not satisfied with it. Maybe none're good answers.
What do you think about it?

I also think none of those answers are good answers.

I think you need a word that suggests quantity or amount

[Sophie]

Hi Benjamin!
According to you, what should the answer be, apart from the answers given which isn't suitable?

umm well the sentence is a bit ambiguous and could have several things there.
What is certain is the speaker of the sentence has some information but needs more.

So to point you in the right direction...you could say "the level of information is far from enough"
information is an "uncountable noun" and so always needs a word to help quantify it.
its like "water"
you can't have a singular water...you need to quantify it with words such as "a cup of water" or "a bottle of water" or "a sip of water"

information is the same. So that's why I think something quantifying the information rather than describing the information is needed.

[Sophie]

Well, I've got it. Thanks a lot.

My view is that B was indeed intended to be the right answer, but that a different form-- existing-- would be the natural choice if it weren't redundant (existing = that we have now):

The existing information we have now is far from enough.
