Final answer:
I would suggest the 'Enhanced' support plan for your e-retail website as it provides the necessary 1-hour response time to Priority 1 cases while keeping costs in control.
Step-by-step explanation:
Based on the need for 1-hour response times to Priority 1 cases while controlling costs, I would suggest the 'Enhanced' support plan for your e-retail website. The 'Enhanced' plan provides faster response times than the 'Standard' plan, but it does not come with the higher cost of the 'Premium' plan. With the 'Enhanced' plan, your company can prioritize and resolve critical issues in a timely manner without the added expense.
