~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 

log%28b%2C%28sqrt%287%2F12%29%29%29 = %281%2F2%29%2Alog%28b%2C%287%2F12%29%29 = %281%2F2%29%2A%28+log%28b%2C%287%29%29+-+log%28b%2C%283%29%29+-+log%28b%2C%284%29%29%29 = %281%2F2%29%2A%281.21+-+0.68+-+2%2A0.43%29.


Please calculate it yourself and identify the correct option.
