The formula for finding t-score is: 
t = (raw score - mean) / standard deviation
Substituting the values given, 
t = (86 - 88) / 4
t = -0.5
However, since t-score is always positive, we take the absolute value of -0.5 and multiply it by 10 to get an approximate t-score of 5. 
Therefore, the correct answer is B (45).
