We can use the formula P = V^2 / R to find the resistance of the toaster coils.

Given: 
P (power) = 1200 W 
V (voltage) = 120 V 
I (current) = 10 A

Using the formula P = VI, we can also find the current drawn by the toaster coils:

P = VI 
1200 W = 120 V x I 
I = 10 A

Now, we can use both formulas to solve for R:

P = V^2 / R 
1200 W = 120 V^2 / R 
R = 120 V^2 / 1200 W = 12 ohms

Therefore, the answer is B: 12 ohms.
