Concept:
This question tests pronoun-antecedent agreement and context within a multi-part sentence. Let's trace the entities mentioned across the structural components of the sentence:
• In Part A, the subject is "She" (singular), and she interacts with a group denoted by the plural noun phrase "the village women" (plural).
• In Part B, the action is "taught". The recipient of this teaching is written as "her" (a singular objective pronoun).
• In Part C, the subjects taught are finalized as "hygiene and sanitation".
Let's look at the logical breakdown: Who is "She" teaching? She is teaching the people she moved among, which refers back to "the village women". Since "the village women" is a plural noun phrase, using the singular pronoun "her" creates an error in pronoun-antecedent agreement. The correct objective pronoun for a plural group is "them".
If she were teaching herself, it would have to be the reflexive pronoun "herself", but contextually she is educating the local women. Thus, Part B must be corrected from "taught her hygiene" to "taught them hygiene".
The complete corrected sentence should read: "She moved among the village women, taught them hygiene and sanitation."
