I will eliminate "A" only because it contains an unnecessary "their". If a GMAT question contains a "distinguished from" and a "distinguished between" then i always look for other errors.

I have read in prep books that the verb "distinguished" needs to be followed by "from" unless it is followed by "between", indicating that both are right.

Distinguish between X and Y is correct idiom here.. Hence E.
