In situation A, if B2 takes B3's place after an irregularity is discovered, what happens to B3's count?

When B2 takes B3's place after an irregularity is discovered, B2 assumes B3's accumulated count to ensure the integrity of the game's statistics. This means that all the previous actions and counts associated with B3 are retained and carried over to B2. This is crucial because it maintains fairness—B3's achievements and progression in the game are preserved, reflecting their contributions up to that point.

The other scenarios would misrepresent the specifics of the game. For instance, resetting B3's count to zero would unfairly penalize B3 for an irregularity that may not be their fault, while allowing B3 to continue batting would not reflect the necessary correction required by the discovery of the irregularity. Likewise, B2 taking a new count of zero would not accurately portray the situation, as it disregards the previous plays that involved B3. Thus, by ensuring that B2 inherits B3's count, the game upholds its fairness and consistency through the transition.
