• BComputing environment located over the internet
• CA shared computing environment
• DComputing environment dedicated to one company

• A
  4% (1)
• B
  92% (23)
• D
  4% (1)

Explanation

Option B is correct because public cloud refers to computing resources (servers, storage, applications) delivered over the internet by a third-party provider like AWS, Azure, or Google Cloud, accessible to anyone who pays for the service.

• A is wrong - public cloud actually offers scalable, elastic resources, not limited ones; you can provision virtually unlimited capacity on demand.
• C is wrong - while public cloud infrastructure is shared among many customers, "shared computing environment" better describes a general multi-tenant concept and misses the defining characteristic of internet-based delivery.
• D is wrong - that describes a private cloud, where infrastructure is dedicated to a single organization.

Memory tip: Think of "public" as in "open to the public via the internet" - just like a public website is accessible over the internet to anyone, a public cloud is computing power delivered over the internet to anyone willing to pay.
