    First, Multiply 77.1 by 8 to find how many feet the submarine has dived.

    77.1 * 8 = 616.8

    Since the question is asking the submarines position "in relation to the surface," this number needs to be negated.

    616.8 ⇒ - 616.8

    Answer:

    The submarine is at - 616.80 ft in relation to the surface, so option B is correct.
