He always stood right in front of the screen, which was so

Ya i understood there is slight meaning change in D.

Actual contenders are :
B. His standing right in front of the screen always was rather annoying
D. It was annoying that he always stood in front of the screen

Let me try to break down sentence please correct me if i'm wrong

D. It was annoying that he always stood in front of the screen

Here Red is main clause. ( Verb - was annoying)
Blue is subordinate clause (verb - stood)

Coming back to OA

B. His standing right in front of the screen always was rather annoying

standing - Modifier modifies "His" pronoun
was annoying - verb
His - Subject
in front of the screen - Prepositional phrase

Is my understanding correct???


And one basic doubt.. In all these choice there is no actual noun...
Everything are Pronoun, which means there is no proper main Clause..
Is this possible in GMAT ???

13 seconds for this.

A. He always stood right in front of the screen, which was so annoying - Incorrect. "which" incorrectly modifies "screen here.

B. His standing right in front of the screen always was rather annoying - Correct. "His standing.. of the screen" is the subject and "was" is the verb. Makes perfect sense. No SV error. Good to go.

C. That he was always standing in front of the screen was so annoying - Incorrect. Placement of that before the entity it is supposed to modify i.e. "standing in front of the mirror"

D. It was annoying that he always stood in front of the screen -- Incorrect. Awkward sentence construction. Passive construction. I wouldn't rule out because of passive voice but we already have B which is active voice and doesn't contain any error apparently.

E. He was standing right in front of the screen, and was so annoying -- Incorrect. It should be an independent clause after the comma but in this case, it is missing a subject.

Do we have the official explanation for this? Also, what is the source for this question?
