Application virtualization is a software implementation that allows applications and programs to run in an isolated environment rather than directly interacting with the operating system. Sandboxing refers to segregating information or processes for security or testing purposes, but it's not directly related to isolation from the underlying operating system. Abstracting sounds similar to the correct term but is not pertinent to the question, and hosting is provided as an erroneous answer.

Regulated PII data carries legal and jurisdictional requirements, along with official penalties for its misuse or disclosure, which can be either civil or criminal in nature. Legal and protected are similar terms, but neither is the correct answer in this case.
