That the human soul is immaterial is an undisputed fact. Significantly, what is not matter is not spatial and consequently, it is not vulnerable to motion. Evidently, no motion no dissolution. What escapes from dissolution is also free from corruptibility. Therefore, the human soul is immortal. In this argument, one premiss is missing. Complete the argument by choosing from the following :

• A. Nothing is free from dissolution
• B. What is incorruptible is immortal
• C. There is no motion
• D. Matter does not exist
