First, we need to calculate the total change in the stock that increased in value: $57.90 - $54.80 = $3.10 
Next, we need to adjust the change for the stock split factor: $3.10 / 0.123017848 = 25.195 
Then, we add this to the previous day's DJIA value: 12,487 + 25.195 = 12,512 
Therefore, the answer is D.
