which sentence is written correctly?\n○ i wrote a letter (to the mayor) asking for increased funding for our schools.\n○ earning a spot on the football team (which has won the championship the last two years) is quite an accomplishment.\n○ martin a safe driver was able to pass his driving test on the first attempt.\n○ a new bakery, and coffee shop, will open on campus next fall in time for the start of the new fall semester.

Answer

Brief Explanations:

For the first option: Parentheses are used to add extra info, but "to the mayor" is a prepositional phrase, and the structure here is a bit off as the parentheses don't fit the context of non - essential info well.
Second option: The non - restrictive clause "which has won the championship the last two years" is correctly set off by parentheses (or could be commas) to provide extra info about the football team. The sentence structure is correct.
Third option: "Martin a safe driver" is a run - on phrase. It should be "Martin, a safe driver, was able to pass his driving test on the first attempt" with commas to set off the appositive.
Fourth option: The phrase "and coffee shop" is incorrectly used with commas. It should be "A new bakery and coffee shop will open on campus next fall in time for the start of the new fall semester" (no commas around "and coffee shop" as it's part of the compound noun).

Answer:

B. Earning a spot on the football team (which has won the championship the last two years) is quite an accomplishment.
