* Many of them chiseled from solid rock centuries ago

[sumit99]

Many of them chiseled from solid rock centuries ago, the mountainous regions of northern Ethiopia are dotted with hundreds of monasteries.
(A) Many of them chiseled from solid rock centuries ago, the mountainous regions of northern Ethiopia are dotted with hundreds of monasteries.
(B) Chiseled from solid rock centuries ago, the mountainous regions of northern Ethiopia are dotted with many hundreds of monasteries.
(C) Hundreds of monasteries, many of them chiseled from solid rock centuries ago, are dotting the mountainous regions of northern Ethiopia.
(D) The mountainous regions of northern Ethiopia are dotted with hundreds of monasteries, many of which are chiseled from solid rock centuries ago.
(E) The mountainous regions of northern Ethiopia are dotted with hundreds of monasteries, many of them chiseled from solid rock centuries ago.


The choice here is clearly between D and E.

Why is D wrong? Is it because of Many of which or are chiseled? Also why?

[rtfact]

I think D is wrong because it should read "were chiseled".
However, I do not understand why C is wrong.

[sumithshah]

Are dotting implies that it is a continuous action (they are still dotting ) this is not possible - hence C is wrong
