To answer the question about types of commission, we should first understand what commissions are generally used for in sales and business. Commissions are incentives that encourage salespeople to sell more products or services. Each option provided pertains to different structures of compensation, but one of these is not a type of commission.

1. Interest: This typically refers to a fee paid for the use of borrowed money or a return on investment, and not a commission structure.
2. Graduated: This is a type of commission that increases as sales increase, rewarding higher performance.
3. Straight: This is a straightforward commission structure where the salesperson earns a fixed percentage on each sale.
4. Salary Plus: This option combines a base salary with commission, providing a stable income along with performance incentives.

Conclusion

The correct answer is Interest, as it does not qualify as a type of commission structure. It relates to finance and economics rather than sales compensation.
