Step-by-step explanation:
The specific cloud computing feature that helps businesses serve their customers without service interruption and in a cost-effective way is c) Elasticity.
Elasticity refers to the ability of a cloud computing system to dynamically allocate and reallocate resources based on demand.
This means that businesses can quickly scale up or down their computing resources as needed, ensuring that customer needs are met without delays or disruptions.
By only paying for the resources they use, businesses can also save costs, making elasticity a cost-effective feature of cloud computing.
