Multiple answer teaser

    in a question we have lines of data a student needs to circle the right answer among the few proposed
    the option are:

    a. only one line has the right data.
    b. only two lines has the right data.
    c. only three lines has the right data.
    d. " 4 " "


    on the last option it says
    "all the lines are correct"

    which option the student must choose to get the full score of the question?
    (notice the data in the chosen line has to be correct)

    Choice A is the correct answer.

    It cannot be A...in the question it says lines of data, not a line. But if it was b, that would mean b and c or d, so that would mean if it was b and c, then it would be b,c, and d, and d is that all of them are right...so this is impossible.

    Am I right? (I don't need to ask...I am 99.99% sure I'm right...)
