To calculate the T-score, we need to use the following formula:

T-score = (raw score - mean score) / standard deviation * 10 + 50

Substituting the values given:

T-score = (86 - 88) / 4 * 10 + 50 
T-score = (-2) * 10 + 50 
T-score = 30

Therefore, the approximate T-score for Claus is 30, which corresponds to choice B.
