Which of the following is NOT a way our right to privacy can be infringed?

Informed consent is not a way in which the right to privacy can be infringed upon. Instead, informed consent is a fundamental principle in which an individual gives permission for something to happen, typically after being fully informed about the implications and potential consequences. This means that an individual's right to privacy is respected because they have agreed to share their information or participate in a specific activity willingly and with a clear understanding.

In contrast, the other options represent violations of privacy. Public disclosure of private facts involves sharing personal details about someone without their consent, which could harm their reputation or emotional well-being. Invasion of solitude pertains to intruding upon an individual's personal space or privacy without permission, such as unauthorized surveillance. Appropriation for commercial use involves using someone's name, image, or likeness for personal gain without their consent, which can exploit their identity for profit. These actions clearly breach the boundaries of an individual's right to privacy, highlighting why informed consent, which embodies respect for personal autonomy, is the correct answer in this context.
