Under the CPRA, the right to opt out specifically applies to which processing activities?

The California Privacy Rights Act (CPRA) expands consumer privacy rights, particularly focusing on how personal data is collected and processed. Under the CPRA, the right to opt out specifically applies to activities deemed as "selling" and "sharing" personal information.

Choosing both selling and sharing as the correct answer highlights the importance of consumer agency over their personal data. "Selling" refers to the exchange of personal information for monetary value, while "sharing" relates to disclosing personal information to third parties for a variety of purposes, such as marketing. The law empowers consumers with the right to prevent businesses from selling or sharing their data without consent, thereby fostering a greater sense of control over personal information.

The other processing activities mentioned in the options—combining datasets—does not inherently involve selling or sharing, and thus does not trigger the same opt-out rights as specified under the CPRA. This distinction reinforces the primary focus of the CPRA on consumer consent regarding the sale and sharing of personal information, making the combination of options A and C the correct answer.
