The correct answer is B. Economies of Scale.

Public cloud providers can offer lower costs to their customers due to economies of scale. Public cloud providers have a large customer base, which enables them to spread their fixed costs across a larger number of customers. This helps to lower the overall cost per customer.

For example, a public cloud provider can purchase a large quantity of hardware, such as servers or storage devices, at a discounted rate due to their volume of purchases. This cost savings can then be passed on to their customers in the form of lower prices.

In addition, public cloud providers can also benefit from economies of scale in their data centers. By having a large number of customers using their services, they can maximize the utilization of their data center resources, which can lead to lower costs per customer.

While the use of hardware from cost-effective vendors (A) can also help public cloud providers lower their costs, it is not the primary reason for cost-benefits. Automatic updates for infrastructure of PaaS and SaaS offerings (C) can improve the efficiency of the cloud services, but it is not a direct factor in the cost-benefits. Therefore, the correct answer is B. Economies of Scale.
