Final answer:

The available information doesn't provide specific values or conditions regarding the displacement, forces, or properties of the block, making it impossible to determine the comparison between the work done by the spring and friction.

D) Not enough information to determine.

Step-by-step explanation:

The determination of work done by the spring and friction necessitates specific values or conditions related to the displacement, forces involved, and properties of the block. Without these details, it's impossible to ascertain the comparison between the work done by the spring and friction.(D)

Work done by a force is given by the equation W = F ⋅ d ⋅ cos θ, where F is the force, d is the displacement, and θ is the angle between the force and displacement vectors. For the spring, the work depends on the spring force and the displacement, while for friction, it relies on the frictional force and the displacement.

The work done by the spring is contingent on the displacement against the spring force. It's determined by the integration of the force over the displacement. Similarly, the work done by friction relies on the force of friction acting over the displacement. The comparison between the two depends on their magnitudes and directions relative to the displacement, which are unspecified in the question.

Without explicit values for the forces exerted by the spring and friction, their behavior along path 2, and the displacement magnitude and direction, it's unfeasible to definitively state which force does more work. Therefore, the answer remains indeterminate without the necessary quantitative information to calculate and compare the work done by the spring and friction along the specified path.
