The electron cloud model was conceived by Richard Feynman in an attempt to accurately depict the probability density of an electron as it occupies the space surrounding the nucleus of an atom or molecule.

A. The electron cloud model was conceived by Richard Feynman in an attempt to accurately depict the probability density of an electron as it occupies the space surrounding the nucleus of an atom or molecule

B. The electron cloud model was conceived from Richard Feynman in an attempt to accurately depict the probability density of electrons as they occupy the space surrounding the nucleus of an atom or molecule

C. In an attempt to accurately depict the probability density of electron as it occupies the space that surrounds the nucleus of an atom or molecule, Richard Feynman conceived the electron cloud model

D. For an attempt to accurately depict the probability density of an electron as it occupies the space surrounding the nucleus of an atom or molecule, Richard Feynman conceived the electron cloud model

E. In an attempt to depict accurate the probability density of an electron as it occupies the space surrounding the nucleus of an atom or molecule, Richard Feynman conceived the electron cloud model

+1 for A.

A. The electron cloud model was conceived by Richard Feynman in an attempt to accurately depict the probability density of an electron as it occupies the space surrounding the nucleus of an atom or molecule --> Correct usage of idiom and preposition

Hence, A.

I do not like that passive voice in A. Option C seems more familiar to me. Cant find any issue in the sentence.

Can just the omission of an article render an answer choice incorrect? C looks fine and better than A but only has a missing article "an" before electron. Does it matter much?

What is antecedent of pronoun it,
in my opinion, antecedent can be an electron, probability density or The electron cloud model.
Can somebody clarify on this issue?

"It" refers to electron only.
Model or density cannot occupies the space around nucleus of an atom or molecule.

The author's intention is to put more emphasis on the cloud model and not on Richardd. Option A is in passive and thus puts more emphasis on the model which is the subject.
Option C is grammatically correct but fails to emphasize the model.

>>Grammatically correct. Theauthor purposely writes the sentence in passive voice so as to put more emphasis or indirectly modify the subject THE ELEC CLOUD. (in an attempt to accurately depict the probability density of an electron as it occupies the space surrounding the nucleus of an atom or molecule.) the bracket part puts more emphasis on the cloud.

A. The electron cloud model was conceived by Richard Feynman in an attempt to accurately depict the probability density of an electron as it occupies the space surrounding the nucleus of an atom or molecule

C. In an attempt to accurately depict the probability density of electron as it occupies the space that surrounds the nucleus of an atom or molecule, Richard Feynman conceived the electron cloud model>>( GRAMMATICALLY CORRECT BUT LOSES THE TONE OF THE SENTENCE) here the entire emphasis is on Richard and thus the intended emphasis is lost as the electron cloud is placed in the object place.

Whenever two options are grammatically correct , refer to the original sentence and try to understand what the author is trying to say or why is he providing particular information. Whenever you first read the sentence always try to understand the role of each word /phrase. You might have the understanding that active voice is better than passive voice on GMAT. This is actually not a rule you should hold on to. To try and make a sentence concise we often distort the intent and hence the actual intention of the author is lost.
