Choose the one which conveys the meaning of the sentence correctly.

Correct answer: With a frown on his face, the teacher asked the students to leave the room.

Explanation: The introductory phrase "With a frown on his face" clearly modifies "the teacher" because it immediately precedes the clause describing the teacher's action. This placement removes ambiguity and produces a natural, clear sentence.

• Sentence "The teacher asked the student to leave the room with a frown on his face.": This placement makes the sentence ambiguous because "with a frown on his face" could be read as modifying the student or the action of asking.

• Sentence "With a frown on his face, the teacher asked the students to leave the room.": This is clear and unambiguous: the teacher is the one who has the frown while asking the students to leave.

• Sentence "With a frown on his face, the teacher asked the students to leave the room." (duplicate): Identical wording is also correct; the presence of a duplicate option appears to be an error in the options list.

• Sentence "The teacher asked with a frown on his face the student to leave the room.": The modifier interrupts the verb and its object, producing an awkward, unnatural word order. Repositioning the modifier to the start clarifies that it refers to the teacher.

Conclusion: "With a frown on his face, the teacher asked the students to leave the room." is the clearest and grammatically correct choice because it unambiguously shows that the teacher had the frown when making the request.
