    I simply do not understand the question. I just randomly guess D as the answer. Please someone explain me.

    Assuming I understand it correctly, if 1 mile has 264 lines then 9 miles should have 9 X 254 lines? so my take would be - None of the above.

    264 is close to 300

    wouldn't 9 x 300 = 9 x 3 hundred be a valid estimate?

    Then I suggest you look up the word "estimate".
