I wish there was a comma after radium...the answer could hav be A. Buh no comma xo the right answer is C ... Plz myschool...notify us when correction is beinq made....

Hw will radium discover Maria instead of d reverse being d case...i strongly disbelief A

If the correct option is D,then the question is wrongly composed! It should be "Radium ..... by Maria Sklodowska Curie"

the question is wrong. its in jamb past question. "radium ____by Maria Sklodowska Curie... so the answer is D

Thanks for your contributions. The question has been reviewed and correction has been made.

The correct answer is "D" though, option "E" also fits in the absence of option "D" because it depends on the context of the sentence.
