Both options A and B can be used to perform a case insensitive comparison of two strings. Option A, str1.equalsIgnoreCase(str2), directly returns a boolean indicating whether the two strings are equal regardless of case. Option B, str1.compareToIgnoreCase(str2) == 0, compares the two strings lexicographically, ignoring case differences, and returns an integer indicating whether they are equal (with a return value of 0 indicating equality). Therefore, both options A and B can be used to test the equality of two strings in a case insensitive manner.
