Selected Answer: D

What you should know: 1. No Upfront - Pay nothing at the time of purchase. Payments are spread out monthly over the term (1 or 3 years). Lowest savings with high flexibility. 2. Partial Upfront - Pay a portion of the cost upfront, with reduced monthly payments over the term. Moderate savings with moderate flexibility. 3. All Upfront - Pay the full cost upfront at the time of purchase. No additional payments required during the term. Highest savings with the least flexibility. Merely by the question, option D would be the answer because it's best for companies with a stable workload, long-term commitment, and sufficient budget for upfront payments. Just to add something, generally option C would be the best in real world cases because it strikes a good balance between savings and upfront investment, and uitable for mid-term commitments with moderate budget flexibility.
