What is the result if B5 hits a home run but passes R1 after rounding first?

In this scenario, when B5 hits a home run but passes R1 after rounding first base, the situation is governed by the rules of base running and appealing plays in baseball or softball.

According to the rules, a base runner must touch each base in the proper order. If B5 fails to do so by passing R1, and the defensive team appeals the play before the next pitch, B5 can be called out for failing to touch the base, which means all runs that were scored as a result of that play are affected. In this case, since R1 was passed by B5, R1 is also out upon appeal because B5 did not legally complete his trip around the bases.

Therefore, B5 is ultimately declared out for missing the base, and the appeal on R1 means that R1 is also out, making this the correct interpretation of the action that leads to B5's out and R1's out as a result of the appeal.
