Explanation:

Describing a person or thing before relating him/her to the reason for his or her action that is to be taken or will be taken in future is the best way to start a sentence that involves Action and reasons behind an action.

The first sentence is complete because it describes Esther talks about the occasion and talks about the action she should take. it is also a correctly written sentence. unlike other sentences that either lack completeness or is wrongly constructed.
