why do you think D is the correct choice?

3. I am not quite sure. but it makes sense the most out of these. could you please tell me?

4. 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.

6. 264 is close to 300

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

That's what I understand the problem.

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