To determine the category of software maintenance used for modifying software to match changes in the ever-changing environment, we need to analyze the options provided.

A) Corrective maintenance is typically used to fix defects or bugs in the software, rather than adapting it to changes in the environment.

B) Adaptive maintenance is the category that focuses on modifying software to accommodate changes in the environment. This includes updating the software to work with new hardware or software platforms, as well as making changes to comply with new regulations or standards.

C) Perfective maintenance involves making enhancements to the software to improve its performance, usability, or maintainability. While this category may indirectly address changes in the environment, it is not specifically focused on adapting to them.

D) Preventive maintenance aims to proactively identify and fix potential issues before they cause problems. It is not directly related to adapting software to changes in the environment.

E) None of these options specifically address the modification of software to match changes in the ever-changing environment.

Based on the provided options, the category of software maintenance that is used for modifying software to match changes in the ever-changing environment is B) Adaptive maintenance.
