B.Stays the same
C.The pond overflows
D.Water level drops
Hint: It's a 3-word phrase with 15 letters, starting with "W".

When in the boat, the brick displaces its weight in water. When in the pond, it only displaces its volume. Since it is denser than water, its volume displacement is less than its weight displacement.
