Explanation

Regularly updating firmware on IoT devices is a critical security best practice because firmware updates patch known vulnerabilities that attackers could exploit. IoT devices are frequent targets precisely because they are often neglected after deployment. Option A (leaving default credentials unchanged) is a major security risk, as attackers commonly use default credentials in automated attacks. Option B (connecting to unsecured Wi-Fi) exposes the device and network to interception and unauthorized access. Both A and B represent poor security hygiene, making C the only correct answer.
