Idiom: distinguish between x and y

I know distinguish x from y is an idiom too.

I read on gmat forums that distinguish between X and Y is used for contrast
and distinguish x from y for when they are kind of similar.

Is it B?

the right idiom is
"that distinguish x and y"
the subject of the sentence (national meteorological service) issues what----->official guidelines
these official guidelines are doing what-----> distinguishing between two things
in order to make it clear, the correct version used tropical storms first +comma +which to describe that how they may be destructive.
for me it should be B

I think the word "same" makes the difference here. And as Sparkles suggested, ans could be E rather than B... What say?

If i were u, i would choose A

as far as i know "distinguish x from y" is a right idiom but it is suspected most of the time and gmat really dont like it.

This is a tricky proposition.

Usually distinguish from and distinguish between are acceptable. But, if we are concerned about GMAT, then we have to go according to what they say is correct!

Also distinguish from seems more appropriate when one says "Distinguish car from bike"
and "Distinguish between cars or storms or trees"(similar properties)

Hence, here I prefer "distinguish between X and Y" idiom.

Before that,let us see, what other things can be incorrect here:

A=Incorrect, distinguish word has to be included.

After the comma the usage of which and perhaps

Here I feel the usage of which is important!

Whether whatever information about the storms is essential or non essential?

Based on such things we can use POE and arrive at the final answer!
