   A large enterprise is deploying a new customer relationship management (CRM) system on a shared server that also hosts a legacy billing system and a reporting tool. The coexistence test team has identified the following potential conflicts: (1) both the CRM and billing system use the same database schema and may lock tables; (2) the reporting tool uses a scheduled job that runs at the same time as the CRM's nightly batch process; (3) the CRM installer modifies a shared environment variable that the billing system relies on. The team has a limited test window and must prioritize which conflicts to test first. The operational profile for the CRM shows that the nightly batch process is used 40% of the time, while the reporting tool's scheduled job runs only 5% of the time. Which conflict should the team test first, and why?

   • ATest the database table locking conflict first because it affects the most frequently used operation (nightly batch) and could cause data corruption.
   • BTest all three conflicts simultaneously in a single test run to save time.
   • CTest the reporting tool scheduling conflict first because it is the most predictable and can be tested quickly.
   • DTest the environment variable conflict first because it is the easiest to reproduce and fix.
