A Key Difference Between Cause Marketing and an Outright Charitable

A key difference between cause marketing and an outright charitable contribution is:

A) charitable donations are contributed at the sole discretion of the firm; with cause marketing the amount is directly affected by the consumers' purchases.
B) a charitable contribution counts as a higher tax deduction.
C) cause marketing is generally linked to public causes and concerns and straight charitable contributions are generally given to private institutions.
D) there is no limit to the amount of charitable deductions a firm can make, but a firm is limited to the number of cause marketing efforts made in the course of one year.
