Which selective retest technique selects every test case that causes a modified program to produce a different output than its original version?
Coverage
Minimization
Safe
Maximization
Explanation:
Safe techniques do not focus on coverage criteria, instead they select every test case that cause a modified program to produce different output than its original version.
