An actual question will not give you such choices..
the underlined portion cannot start with the names ' Marie...'
It puts three items - radium, Marie curie and Andre - parallel and makes it illogical. AND three choices have same mistake !!!
Eliminate C,D,E

Now in original..
The modifier WHICH wrongly tries to modify result of previous clause.
B corrects it by making it an absolute modifier and describing about the result of previous clause.

(A) a luminescent radioactive element, was isolated as a pure metal by Marie Curie and André-Louis Debierne, which led (which illogically modifies MC & ALD)
(B) a luminescent radioactive element, was isolated as a pure metal by Marie Curie and André-Louis Debierne, an advance that led( an apt choice,correct modifier error)
(C) Marie Curie and André-Louis Debierne isolated radium, a luminescent radioactive element, as a pure metal in 1910, which led (modifier error)
(D) Marie Curie and André-Louis Debierne isolated radium as a pure metal in 1910, a luminescent radioactive element, leading (same as in C)
(E) Marie Curie and André-Louis Debierne who isolated radium, a luminescent radioactive element, as a pure metal in 1910, leading( same as in C)
Choice B is correct

Split 1:

No verbs in D and E. Both are fragments
Eliminate D and E

Split 2:
'which' modifies wrong entities in A and C
Eliminate A and C

B is our winner

It seems in case of C,D and E the underline should start from beginning of the sentence otherwise Radium is redundant.
in A the modifier which is incorrectly modifying André-Louis Debierne
so B

Simply Answer is B

Official Explanation:



Answer - B
Concepts tested: Modifiers


A – The phrase ‘which led’ refers incorrectly to Debierne, and 1910 and element respectively.
B – This option uses an absolute phrase – “an advance that led …” to refer to the entire preceding clause.
C – Same as A D – The phrase ‘a luminescent radioactive element’ refers incorrectly to 1910.
E - Sentence fragment because it lacks a main verb – notice the use of ‘who isolated radium’.

Hello aragonn

What is the role of the comma(,) in the Option B. Is it necessary?
