* Sentence A: "A Fran bought new dress for her graduation ceremony" is grammatically incorrect and lacks clarity. There is no relative pronoun used.
* Sentence B: "I dislike driving on road lot of curves" is also grammatically incorrect. It needs articles ("a" and "with") and a clearer subject. There is no relative pronoun used.
Here's an example of a sentence with a relative pronoun forming a dependent clause:
* "The dress that Fran bought for her graduation ceremony was beautiful."
In this sentence, "that" is the relative pronoun. It connects the dependent clause "that Fran bought for her graduation ceremony" to the noun "dress". The dependent clause provides more information about the dress.
