Final answer:
The true statement is that all versions of substance dualism entail that the mind causally interacts with the body. This encapsulates the fundamental interactionist belief of substance dualism, where the non-physical mind and the physical body are said to engage in causal relations.
Step-by-step explanation:
The statement that is true among the options given is C. all versions of substance dualism entail that the mind causally interacts with the body. Substance dualism posits that the mind and body are two distinct substances that engage in causal interaction; this is a central tenet to the theory. According to substance dualism, these interactions take place even though the mind, a non-physical entity, is fundamentally different from the physical body.
Conversely, property dualism simply asserts the existence of both physical and non-physical properties, and does not necessarily imply the same interactionist commitments. Therefore, property dualism does not entail substance dualism. Lastly, the claim that substance dualism and physicalism could both be true is incorrect, as physicalism denies the existence of any non-physical substance, which is a core tenet of substance dualism.
