I vote for B too.
First option compares 'tungsten' with 'acrbon filaments'.
Option C and D seem to suggest that the Discovery was working n the laboratories.
Option E suggests the ability to be working in the Laboratories.
I vote for B too. First option compares 'tungsten' with 'acrbon filaments'.
I agree with this statement.

C, D and E are typical examples of Errors in Dangling modifiers.
In my opinion , answer is A or B.
B is more "parallel" construction ...so then... B!

look at comparisons:
A. tungsten - carbon filaments B. tungsten filaments - carbon filaments
Maybe it isn't a classical example of parallelism, but I used " "
EDIT : my bad pitt. i will try again. Bold part represents modified post
This is some good stuff from kaplan.
The Official Answer from kaplan is A...and i got it wrong.
In our case,
Dr Irving discovered that the tungsten can be used in incandescent lamps.
Thats the original idea of the sentence..isnt it.
in B..does that idea remain the same.
B changes the meaning. It says ...Dr Irving discovered that tungsten filaments have an efficiency of 12 lumens per watt... But , thats not correct...isnt it.
Dr Irving only discovered that the tungsten can be used in incandescent lamps. we cant change the meaning of (A).
i dont think " tungsten" and " carbon filaments" is a big issue here
Do you even see a comparison?
i dont see "than" , "compared to" or " compared with"

I didn't say that comparisons are from sentences...i said to look at mentioned compratisons...in sense of parallelism..
@Pretorian..you got a point there, B changes the meaning...
