b. portability
c. maintainability
d. usability

Reliability is the agile MIS infrastructure characteristics refers to the ability of an application to operate on different devices or software platforms, such as different operating systems.

A. Reliability

Explanation:

In MIS infrastructure main issue is “RELIABILITY”,  if reliability fails whole infrastructure fails in the organization. Suppose we implement multiple infrastructures and connected each other and data transaction processed with negative impact then reliability fails there.

Others such as portability or maintainability and usability plays based on reliability only. Once reliability fails others automatically fails in MIS infrastructures.

As operating system and software platform “reliability” is only solution and preferred one. Others such as portability, maintainability and usability are operational usages.
