A.
a 33-newton force pointing upward
B.
a 1-newton force pointing upward
C.
a 33-newton force pointing left
D.
a 0-newton force pointing downward
E.
a 1-newton force pointing right

Answer:
to create a net force of zero on the object you must apply:
33 Newton upwards.
Explanation:
For this case, the first thing we are going to do is define a reference system.
We define the vertical axis of the reference system, pointing upwards.
Therefore, doing summation of forces in vertical direction we have:
Then, since we want the net force to be equal to zero, then:
From here, we clear the force that we must apply on the object:
The positive sign means that the force points upwards.
