How is possession of child pornography defined?

Possessing child pornography is specifically defined as having or controlling material that depicts a person under the age of 18 engaging in sexual conduct. This definition emphasizes the nature of the material rather than actions involving minors in terms of sexual relations or distribution.

The clarity in this legal definition highlights that the mere possession or control of such materials is a serious offense, separate from the act of engaging in sexual activities with minors or disseminating inappropriate content to them. The focus is on the representation of minors in sexual contexts in the material itself. Therefore, option B is the correct choice, as it aligns with the legal understanding of child pornography possession. The other options refer to distinct actions that do not encompass the specific legal definition of possession.
