Answer:
<em>Building the house on the top of a hill, she became famous.</em>
Explanation:
The given sentences are two independent clauses that talk about a single noun/ pronoun (in this case). And to rewrite them, we need a change in the way the sentence is constructed, depending on what the requirement is.
With the need to start the sentence with "building", we can rewrite the given sentences as "building the house on the top of a hill, she became famous." This makes the first part a dependent clause, starting the sentence with a participial phrase and also a gerund "building", thus the need for a comma after "hill".
Thus, the new sentence will become
<em>Building the house on the top of a hill, she became famous.</em>
The point of view reflects the perspective of the story. The person is in terms to the narrator. Thus, the answer is the last one.
