The process capability index can be calculated using the formula: 
Cp = (upper specification limit - lower specification limit) / (6 * standard deviation)
Substituting the given values, we get:

Cp = (15.2 - 15.0) / (6 * 0.04)
Cp = 0.2 / 0.24
Cp = 0.8333

Therefore, the process capability index is 0.8333, which is closest to option B.
