Construction of the Roman Colosseum, which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, was completed a decade later, during the reign of Titus, who opened the Colosseum with a one-hundred-day cycle of religious pageants, gladiatorial games, and spectacles.

A. which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian,

B. officially known as the Flavian Amphitheater, begun in A.D. 69, during the reign of Vespasian, and

C. which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, and

D. officially known as the Flavian Amphitheater and begun in A.D. 69, during the reign of Vespasian it

E. officially known as the Flavian Amphitheater, which was begun in A.D. 69, during the reign of Vespasian, and

OA is C,

my doubt is why is b incorrect?

A) cant we use begun here? or should begun be preceeded by "had"?
B) why is "which" needed here ?

A. which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, missing "and"

B. officially known as the Flavian Amphitheater, begun in A.D. 69, during the reign of Vespasian, and

C. which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, and

D. officially known as the Flavian Amphitheater and begun in A.D. 69, during the reign of Vespasian it

E. officially known as the Flavian Amphitheater, which was begun in A.D. 69, during the reign of Vespasian, and

IMO: C

"which was officially known as the Flavian Amphitheater" - Extra information. Ignore this and read out the options

begun is a past participle. We cannot use it as a verb here. It needs auxiliary verb to make sense as in have begun/has begun/had begun

A/D - and is missing - wrong
B - begun seems to modify amphitheater.
E - which was begun - Changes the meaning, construction began in AD69 not Amphitheater.

IMO C.

There is however one small doubt which I would like to clarify myself from this question.

Construction of X, which was - X of Y, which was - Which seems to refer to construction rather than Colosseum in option C, is it right ?
Getting defeated is just a temporary notion, giving it up is what makes it permanent.

Constrution is not officially known as Flavian Amphitheater. We need to use which to make it clear that it is Roman Colosseum which is officially known as Flavian Amphitheater.
