What will occur when the trough of Wave A overlaps the crest of Wave B?

Destructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.
Constructive interference will occur, causing the new wave to have more energy than Wave A or Wave B.

Explanation: a crest (positive displacement) overlapping a trough (negative displacement) causes their displacements to cancel, reducing the resultant amplitude (possibly to zero if they are equal). Since wave energy depends on amplitude (∝ amplitude^2), the local energy is reduced — overall energy is conserved and may be redistributed.
