Answer:
B. Oftentimes, our family travels to monuments and museums.
Explanation:
Oxymoron is a figure of speech in which contradictory words are placed in the same sentence. These contradictory or opposite ideas bring a literary effect and helps the writer present the ideas more exclusively.
The sentence in option (b) presents an example of an oxymoron. The words that present the opposite or contradicting ideas are 'often' and 'times'. The family here travels to monuments and museums 'oftentimes' that brings the meaning of 'often' and 'times'.
The prepositional phrase comes at the end of the sentence: in one hand.
Here, the preposition is "in" and the entire prepositional phrase is "in one hand." This phrase is describing the location of the rattle.
