Information security aims to protect information assets against threats and vulnerabilities that could lead to unauthorized access, disclosure, alteration, or destruction. By implementing effective security measures (such as access controls, encryption, and monitoring), an organization reduces the likelihood of vulnerabilities being exploited and mitigates the potential impact of risks. According to ISO/IEC 27005, risk management in information security includes identifying, assessing, and applying controls to reduce both the likelihood and impact of potential risks. Thus, option A is correct because it acknowledges the role of information security in reducing the impact of risks. Option B is incorrect because information security is a key component of risk management, and option C is incorrect because information security does not eliminate risks entirely; it mitigates their impact.
