Final answer:
Without specific information on frameworks and privacy as a core tenet, none of the multiple-choice answers about the percentage of frameworks can be selected. The information provided points to public concerns about data collection by companies and the government, not directly to frameworks.
Step-by-step explanation:
The question regarding the percentage of frameworks that include privacy as a core tenet is not directly answerable with the information provided. None of the statistics reference frameworks specifically or their approach to privacy as a core tenet. Instead, the information provided gives insight into public perception about data collection practices by companies and the government. For example, 79 percent of people expressed concern over data use by companies, while 64 percent were concerned about government data use. Additionally, 81 percent felt they had little control over the data collected by companies, and 84 percent felt the same about government data collection.
Concerning the percentage of countries with a unicameral legislature, the options given do not match the provided information. Thus, without specific information on frameworks and privacy, none of the multiple-choice answers (50%, 85%, 25%) can be conclusively selected in this context.
