I believe A, D, and E are the correct answers.
I don't think the title of a line graph is completely necessary, as long as the viewers know what the graph is showing.
Also, color is not important if you only have 1 line. If you have multiple lines though, then you would probably need color.
But it is extremely necessary to have equal intervals on your graph, otherwise it just won't make sense.
Also, if you don't have an X axis or a Y axis, then half of your graph is missing!
I'm not sure if it's as necessary to have a grid, but the graph might be hard to read without it. So, I would put that down as an answer.
