What does the dissemination of obscenity to minors require?

The correct choice in this context is that the dissemination of obscenity to minors requires knowledge of harmful matter. This means that for someone to be held legally accountable for distributing obscene material to minors, they must be aware that the material in question is considered harmful or obscene.

In legal terms, to demonstrate culpability in such cases, the prosecution typically needs to show that the individual knowingly engaged in the act of distributing material deemed inappropriate for minors. This recognizes the importance of intent and awareness in criminal liability, particularly in the safeguarding of minors against exposure to harmful content.

The other options, while they may touch on relevant concerns, do not accurately reflect the legal requirements necessary for a charge related to the dissemination of obscenity. For instance, simply being aware of a minor's presence does not imply knowledge of the content's nature. Similarly, adult supervision or parental agreement do not alleviate responsibility if the disseminator knows the material is obscene. Thus, the critical factor in establishing this form of criminal liability is indeed the knowledge of harmful matter being distributed.
