Given $b>1$, $\sin x>0$, $\cos x>0$, and $\log_b \sin x = a$, determine the value of $\log_b \tan x$.
A) \( a - \frac{1}{2} \log_b (1+b^{2a}) \) \\
B) \( a + \frac{1}{2} \log_b (1-b^{2a}) \) \\
C) \( a - \frac{1}{2} \log_b (1-b^{2a}) \) \\
D) \( \frac{1}{2} \log_b (1-b^{2a}) - a \) \\
E) \( \text{none of these} \)
