Best answer

(a) the path taken by the suitcase

(b) the time taken by you in doing so

(d) your weight.

Explanation: 

Since the force applied by me is a conservative force, the work done by me on the suitcase does not depend on the path taken by the suitcase. (a). 

Work done is the product of force and displacement. It does not depend on time. (b). 

It does not depend on my weight because we are calculating work done by me on the suitcase. (d). 

But it depends on the weight of the suitcase. So (c) is not correct.
