“...to destroy the windmill, the building of which had aroused furious jealousy in him”
Regarding the above quote from Animal Farm, I'm confused about the use of the preposition "of" and relative pronoun "which". Please explain the above sentence in the grammatical context. Following are the structure which make sense to me.
"...to destroy the windmill, the building which had aroused furious jealousy in him"
or
"...to destroy the windmill, the building of which he had been furiously jealous."
or
".. to destroy the windmill, the building which he had been furiously jealous of."
