What is the main difference between Solver and Goal Seek?

a$.$

Solver is limited to linear optimization problems, while Goal Seek can handle nonlinear optimization problems.

b$.$

Solver and Goal Seek both serve the same purpose and can be used interchangeably.

c$.$

Goal Seek is more advanced and feature$-$rich compared to Solver for complex problem$-$solving tasks.

d$.$

Solver is a tool that can handle complex problems with multiple variables while Goal Seek is a simpler tool that can only find a single input value to achieve a specific target output.

e$.$

Goal Seek is used for optimization tasks, while Solver is used to find a specific input value for a target output.
