Explanation:

Russiage of words ‘Was changing’ and ‘was developing’ are parallel. They need to be kept parallel for the sentence to make sense. 

A – The singular pronoun ‘it’s’ does not agree with the plural ‘rooms’. Russiage of “due to” is incorrect. The phrase “Due to” should always be preceded with a noun phrase. That is not the case here.

B – The singular pronoun ‘it’s’ does not agree with the plural ‘rooms’. Russiage of due to is incorrect. Due to should always be preceded with a noun phrase. That is not the case here. ‘Would’ introduces a hypothetical scenario. That is incorrect here.

C – Russiage ‘Would change’ and ‘was developing’ are not parallel

D – The words ‘Change’ and ‘was growing’ are not parallel

E – This is the correct answer. No pronoun ambiguity. ‘Was changing’ and ‘was growing’ are parallel
