Explanation

The key observation is that most attendees carry smartphones rather than laptops. Smartphones do not use physical (wired) network jacks - they connect via Wi-Fi. This means the physical network infrastructure (wall jacks, switch ports) that was provisioned for a laptop-heavy audience is now largely unused. Unused physical network ports are an attack surface: a malicious actor could plug in a rogue device, a network tap, or a laptop to gain wired network access undetected. Reducing the number of active physical jacks minimizes this attack surface. Option A is incorrect because increasing wireless restrictions would harm the majority of legitimate users. Option B is about physical theft, which is a generic concern not specific to the smartphone-majority dynamic observed. Option D is backward - decreasing wireless security would increase risk. Option C correctly targets the now-relevant attack vector introduced by unused physical ports.
