What is the default behavior of the equals() method for an object regarding comparison?

Compares values
Compares references
Compares hash codes
Compares memory locations

The correct answer is: Compares references

The default behavior of the equals() method for an object is to compare the references. This means that it will check if two objects point to the same memory location. Option A is incorrect because the equals() method does not compare the values of the objects. Option C is incorrect because it does not compare hash codes, it actually uses hash codes as a preliminary check before comparing references. Option D is incorrect because it is redundant and essentially the same as option B. Therefore, the correct option is B as it accurately describes the default behavior of the equals() method for an object.
