Step 1: Understanding the Use of "Neither":
"Neither" refers to two things, and when used with singular subjects, it requires singular verbs and pronouns. The correct form here is "her" because we are talking about one girl at a time. Step 2: Analyzing the Options:
- Neither of the girls solves its task: Incorrect because "its" refers to an inanimate object, but "girls" is a plural subject.
- Neither of the girls solves her task: This is correct because it agrees in number and gender with the singular subject "girl."
- Neither of the girls solves their task: Incorrect because "neither" requires a singular pronoun, not a plural one.
- Neither of the girls solve her tasks: Incorrect because "solve" should be "solves" to agree with the singular subject "girl." Step 3: Conclusion:
The correct sentence is Neither of the girls solves her task.
