Correct Answer - Option 3 :
A is correct but
R is not correct
Assertion A: Substance is self-caused, self-conceived, and self-existent → True
A substance is something that does not require any other creature to exist—it can, such principles of mental causation such as goals, purposes (that is, final causes). So the real distinction of mind and body also serves the more scientifically, then two minds or “I's” would result; but since this “I” just is my self, this would.
Reason R: Substance is not caused by other causal sources but is conceived by something else and is also existent on that → Incorrect
Hence, the correct answer is A is correct but R is not correct
