In a professional work environment, distractions should be minimized, especially when working onsite for a client. The best approach is to put the phone on silent (Option B) to avoid interruptions while remaining professional. Step aside and answer (Option A): Not recommended as it disrupts work and appears unprofessional. Text a reply (Option C): While this may seem reasonable, it still causes a distraction. Ignore the phone and continue working (Option D): While focusing on work is important, completely ignoring calls may not be the best approach. Silent mode ensures work continuity while allowing the technician to check messages later.
