The interrater reliability coefficient can be calculated using the formula: 
(number of agreements) / (number of agreements + number of disagreements)
In this case, the number of agreements is 7 and the number of disagreements is 18 - 7 = 11. 
So the coefficient is: 
7 / (7 + 11) = 7 / 18 = 0.39
Therefore, the answer is B.
