Consider the line integral \[\int\limits_{\text{C}} {\left( {{\text{xdy}} - {\text{ydx}}} \right)} \] the integral being taken in a counterclockwise direction over the closed curve C that forms the boundary of the region R shown in the figure below. The region R is the area enclosed by the union of a 2 × 3 rectangle and a semi-circle of radius 1. The line integral evaluates to
A. \[12 + \pi \]
