Elena Woodward · Answer 1

work = force x distances

A - moving 2 newton's up 0.6 meter = 1.2 joules

B - moving 4 newton's up 0.6 meter = 2.4 joules

C - moving 6 newton's up 0.3 meter = 1.8 joules

D - moving 9 newton's up 0.3 meter = 2.7 joules

The greatest amount of work is in example D.

D is your answer.
