The correct choice identifies that THC, or tetrahydrocannabinol, is the primary psychoactive compound in cannabis responsible for inducing intoxicating effects. When THC binds to cannabinoid receptors in the brain, it alters normal brain function, leading to changes in perception, mood, and cognitive processes. This psychoactive response can include relaxation, euphoria, and changes in sensory perception, which are commonly associated with the experience of being "high" after consuming cannabis.

Understanding the effects of THC is crucial, especially for those in roles related to alcohol and drug service, as it can influence judgment and decision-making. The other options suggest effects of THC that are not aligned with its well-documented impact. For example, the idea that THC relaxes the body without intoxication overlooks its psychoactive nature. Similarly, the claims that THC enhances memory and cognitive abilities or has no effect on perception misrepresent the established understanding of its effects, which can include impairments in memory and perception rather than enhancement. Thus, the selection of the option indicating THC's intoxicating effects accurately reflects its well-researched influence on the brain and body.
