Exactly the same question was posted twice (one right after the other).

Given that the coordinates of point P are (5, y), we know that OM = 5; we have to get the value of ON = y.

Let's take each statement one by one.

(1) The coordinates of point M are (5, 0).

=> OM = 5. We already know this. Moreover, we do not need this information. Insufficient.

(2) The coordinates of point N are (0, −4).

=> ON = y = -4. Sufficient.

The correct answer: B

Hope this helps!
