The correct answer is C. under.
To limbo is to move under a horizontal bar without touching it, typically by bending low at the waist. The bar is typically held by two people, and the person limboing must move under it without touching it with any part of their body. The lower the bar, the more difficult the limbo.
In the sentence “She limboed under the pole,” the word “under” indicates that the woman moved her body under the pole without touching it. The other options do not make sense in the context of the sentence. The word “out of” would indicate that the woman moved her body out from under the pole, but the sentence does not say that she was previously under the pole. The word “over” would indicate that the woman moved her body over the pole, but the sentence does not say that the pole was in her way. The word “move to” would indicate that the woman moved her body to a location near the pole, but the sentence does not say that she was not already near the pole.
