Final answer:
The QoS option that prioritizes VoIP is typically the highest available tier, such as Gold or Platinum, ensuring low latency and minimal packet loss for high-quality voice communication.
Step-by-step explanation:
The QoS option that prioritizes Voice over Internet Protocol (VoIP) is typically the highest level of service available. In a generic tiered QoS model, the options might include Bronze, Silver, Gold, and Platinum, where Platinum would offer the highest level of service. For VoIP, which requires low latency and minimal packet loss to ensure high-quality voice transmission, a higher QoS level such as Gold or Platinum would be prioritized. However, without specific context or definitions of the tiers, it's not possible to determine which exact option would prioritize VoIP. Typically, service providers would define these tiers, and in most cases, Gold or Platinum levels offer the highest QoS necessary for VoIP.
