The correct sentence is A) My car is old and gets bad gas mileage. Having bad gas mileage is an ongoing thing that will never change unless you get a different car, so none of the other choices make sense.
I guess its personal interest really. But if i had to take a wild guess i would say it is D. Why d is because its not really that interesting and stands out because it doesn't give that much detail for what its about. Like why did he retire or what season what is he coaching?
Answer:
it's C because it has the commas placed at correct areas.
the rest of the sentences can be corrected below :-
a. Spider man, who is known for being able to shoot webs from his wrists, is my favourite hero.
b. The children, who were usually happy, had become upset.
d. Peter, who is my best friend, plays the guitar and the piano. hope it helps...
