Option A, `str1.equalsIgnoreCase(str2)`, is the correct method in Java for performing a case-insensitive comparison of two String objects. It compares `str1` and `str2` without considering their case, returning `true` if they are equal ignoring case, and `false` otherwise. Options B, C, and D are not valid methods or operators for comparing strings in Java.
