What is the average number of bulletins being issued monthly if bulletin order number 1 was issued on January 2?

To determine the average number of bulletins issued monthly based on the information provided, we need to consider the rate at which the bulletins are being issued. If bulletin order number 1 was issued on January 2, and assuming the bulletins are issued consistently throughout the year, each month would have a similar number of bulletins released.

Typically, if we observe a consistent issuance throughout the entire year, the number of bulletins could be expected to numerically represent the number of months in the year. Given there are 12 months in a year, and if a bulletin is expected or mandated to be issued regularly, then it is reasonable to assume an average of one bulletin per month.

Hence, the average number of bulletins issued monthly aligns with the total number of months in a year, leading to the conclusion that 12 is the average number of bulletins issued monthly, supporting the conclusion that D is the correct answer.
