The value of the integral $$\oint {\frac{{2{\text{z}} + 5}}{{\left( {{\text{z}} - \frac{1}{2}} \right)\left( {{{\text{z}}^2} - 4{\text{z}} + 5} \right)}}{\text{dz}}} $$      over the contour |z| = 1, taken in the anti-clockwise direction, would be

A. $$\frac{{24\pi {\text{i}}}}{{13}}$$

B. $$\frac{{48\pi {\text{i}}}}{{13}}$$
