While using black-box testing techniques, we drive a set of test cases that satisfy which of the following criteria?i) Test cases that reduce, by a count that is greater than one.ii) Test cases that tell us something about the presence or absence of classes of errors.iii) Execute all loops at their boundaries and within their operational bound.a)i and iiib)ii and iiic)All i, ii and iiid)i and ii

Which of the following is an example of black-box testing?1 pointDeveloping test cases based on typical user behaviorDeveloping additional tests when every if statement does not evaluate both true and false once given the current test suiteDeveloping test cases to exercise error-prone constructsDeveloping additional test cases to force a division by zero
