Two thin, concentric, conducting spherical shells have radii \(a\) and \(b\) (\(a < b\)). Initially, the inner shell carries a net charge \(+Q\) and the outer shell is uncharged. Two independent scenarios are considered:

* Scenario 1: The outer shell is connected to ground while the inner shell remains insulated.
* Scenario 2: Starting from the initial state, the inner shell is connected to ground while the outer shell remains insulated.

Which of the following correctly pairs the final net charge on the outer shell in Scenario 1 with the final net charge on the inner shell in Scenario 2?
