Public opinion is commonly referred to as the composite reaction of the citizenry on

Step 1: Analyze the question The question asks what public opinion is the "composite reaction of the citizenry" on. We need the option that best completes a definition of public opinion.

Step 2: Explain the concept Public opinion is the collective views, attitudes, and beliefs of the people in a society about issues, events, or policies that concern them. It is not limited to government alone. It covers anything of public interest, such as fuel prices, education, security, and taxation. It is expressed through the press, elections, opinion polls, protests, and petitions.

Step 3: Evaluate the options

• A. Matters relating to association: Too narrow. Public opinion is not limited to associations or clubs.
• B. Legal rights of foreigners: Too specific and unrelated to the general definition.
• C. Matters affecting government: This is close, because public opinion often influences government. But it is still too restrictive. People also form opinions on social, economic, and cultural issues that are not strictly governmental.
• D. Key issues that affect them: This matches the broad definition. Public opinion is the combined reaction of the citizens to important issues that concern their lives and welfare.

Step 4: Answer The best answer is D, key issues that affect them.

Tip: In definition questions, choose the broadest option that is still accurate. Public opinion = the people's collective view on issues that affect them, not just government. Watch out for option C, which looks tempting but is too narrow.
