Solution

The correct option is A Yes
Yes Mr. Smith is surely lying. Why is that?
Because the work done by external agent against the conservative field does not depends upon the path. If the final configuration achieved is the same, work done by/against the field is same.

Q. Mr. Smith did 20 J of work in bringing a +2C charge slowly from infinity to a point A against the electrostatic field of a point charge +Q fixed at the origin. If we now define the potential energy per unit charge at point A to be W J/C considering B(5,0) as the reference point. The work done by Smith in taking the same charge from B to A is?

Q. If we say that the electric potential of a point in space is 10 V, what do you understand from it? (Take potential at infinity as 0V)

Q. Work done by the field of fixed static charges on a 50mC charge is -20 J, as the charge moves from point A to point B slowly. The work done by the external agent is?
