A Physics Student in a Hot Air Balloon Ascends Vertically

Multiple Choice

A physics student in a hot air balloon ascends vertically at constant speed. Consider the following four forces present in this situation:

11ec874b_21ea_ddf1_a44c_811fc40246c2_TB34225555_11 1= the weight of the hot air balloon
11ec874b_21ea_ddf1_a44c_811fc40246c2_TB34225555_11 3= the force of the student pulling on the earth
11ec874b_21ea_ddf1_a44c_811fc40246c2_TB34225555_11 2= the weight of the student
11ec874b_21ea_ddf1_a44c_811fc40246c2_TB34225555_11 4= the force of the hot air balloon pulling on the student
-Which two forces form an "action-reaction" pair that obeys Newton's third law?
