Just on simple math, it has to be C (6 times 23 minutes). Although, depending on the capacity of the oven, it can be wildly different.

He can make 2 dozen in 23 minutes, but you need 12 dozen. 2 dozen times 6 = 12 dozen, therefore you need to make six lots of 2 dozen. This means that it will take 6 times as long, so you do 6 times 23, which equals 138.
138 minutes=2 hours 18 minutes.
So, the answer is C :)
