Answer :
Answer: C) Self-recognition
Explanation: It's in the name of the test. The acronym "MSR test" actually stands for "mirror self-recognition" test. To conduct this test, the animal being tested upon will be placed in front of a mirror. Then, a mark will be painted somewhere on that animal. (usually a spot where the animal can't see unless it has the help of a mirror) If that animal makes any sort of movement to indicate that it notices the mark on itself with the aid of the mirror, then that animal is stated to have passed the test.
Thus, the MSR test is entirely a test of self-recognition. Some creatures that have passed this test include great apes, elephants, dolphins, and orcas. However, this test has come under criticism due to not all animals relying on vision to experience the world. Since the mirror test is heavily reliant on vision, creatures that have poor vision or don't rely on vision may "fail" the test but still be capable of self-recognition. Its important to note that the MSR test is not the holy grail when it comes to determining whether animals self-recognize themselves or not. (meaning that it is not 100% conclusive proof that animals either do or don't self-recognize themselves)
