Final answer:
C/QPP calculations for advance/commission payments should be excluded from regular C/QPP calculations.
Step-by-step explanation:
When it comes to C/QPP (Canada/Quebec Pension Plan) calculations for advance/commission payments, the correct approach would be to exclude these payments from C/QPP calculations.
In Canada, C/QPP deductions are based on an employee's regular salary, not on advance or commission payments. These deductions are calculated as a fixed percentage of the employee's regular wages.
Therefore, option B) Exclude from C/QPP calculations is the accurate choice in this case.
