✔ B — If allocated, create a refund, then create a new payment on the correct accountDetailed steps:

Reverse (refund) the incorrect payment

Create a new payment on the correct account

Allocate that payment to the correct invoice

This ensures:

Proper audit trail

Compliance with financial controls

Correct ledger entries

Why the other options are wrongOption

Why Incorrect

A. Allocate payment to Account B invoice
