Final answer:
The compensation expense to be recorded for the stock options by Yang Corporation on December 31, 2014, is $40,000, which represents one year of service period allocated expense from the total $80,000 determined by the fair value option pricing model.
Step-by-step explanation:

Therefore, the correct amount to be recognized as compensation expense on December 31, 2014, is $40,000 (option b).
