A test team is working on a module with a complex decision structure. They have achieved 100% statement coverage but only 80% branch coverage. The project manager wants to increase branch coverage to 100% but has limited time and budget. What is the most effective approach to achieve this goal?

Use a coverage tool to automatically generate test cases

Analyze the uncovered branches and design test cases specifically to exercise those decision outcomes

Add more test cases randomly to increase overall coverage

Switch to statement coverage as the primary metric
