Consider an office visit job interview process where each candidate goes through three activities: verification, written test, and interview. Verification takes $1$ minute, the written test takes $40$ minutes, and the interview takes $10$ minutes. There is one resource dedicated to each activity. A candidate arrives at the office for this interview every hour. Which of the following conclusions can be drawn?$$

Group of answer choices

The interview resource is the bottleneck.

The process is constrained by demand, so adding more resources to increase capacity is unnecessary.

The verification resource is the bottleneck.

The process is limited by capacity, and incorporating an additional resource at the bottleneck could help smooth out the demand.
