Explanation

Bandwidth is the maximum data transfer capacity of a network link (measured in bits per second). As more users simultaneously access an application, they share the available bandwidth. When total demand exceeds capacity, throughput per user drops, causing performance degradation. Latency (A) is the delay in transmitting a packet and is generally not directly proportional to the number of users (though congestion can increase it). Packet loss (B) typically results from congestion or hardware issues, not directly from user count. Jitter (D) is the variation in latency over time and is not the primary constraint tied to increasing concurrent users. Bandwidth is the direct bottleneck for concurrent user scaling.
