Explanation

Daily antivirus updates (option C) strike the right balance for mission critical devices - frequent enough to catch new threat signatures promptly, but not so aggressive that constant update cycles disrupt system stability or performance. Updating by the minute (A) or hourly (B) is excessive and impractical; antivirus vendors don't release signature updates that frequently, and constant update checks consume resources that mission critical systems need for their primary function. Weekly (D) is too infrequent - new malware variants emerge daily, leaving a week-long window of vulnerability that is unacceptable for critical infrastructure. Memory tip: Think "daily like a newspaper" - just as you'd read the news each day to stay current on world events, your antivirus needs a daily refresh to stay current on new threats.
