D) Decrease

Explanation:

When algae dies, decomposing organisms will work on them and this cause the reduction in the amount of dissolved oxygen in the water.

The number of decomposers in the body of water will increase rapidly.
To decompose they need a lot of oxygen which they will remove from the water.
They use the oxygen for their own life activities and they sometime combine it with the algae matter to release nutrients back to the water and atmosphere.
The bloom of the micro - organisms will lead to decrease in dissolved oxygen in water.
