You are right @Praveen.
Because Dupuits formula is for unconfined tube wells.

Given answer is correct one because in question it is given R and Rw.
Which is considered in Dupuit's confined aquifer equation.
In Dupuit's method, the integration limit is considered is R and Rw.
Where R = radius of influence.
Rw = radius of the main pumped well.
While in Thiem's formula for confined aquifers it is given r2 and r1,
In Thiem's formula the integration limit is considered is r2 and r1.
Where r2 and r2 = radii of two observation wells.
