Cho hàm số \(y = f\left( x \right) = \left\{ \begin{array}{l}{x^2} + 3\,\,khi\,\,x \ge 1\\5 - x\,\,\,\,khi\,\,\,x < 1\end{array} \right.\). Tính
\(I = 2\int\limits_0^{\dfrac{\pi }{2}} {f\left( {\sin x} \right)\cos xdx} + 3\int\limits_0^1 {f\left( {3 - 2x} \right)dx} \).
A.\(I = \dfrac{{32}}{3}\)
B.\(I = 31\)
C.\(I = \dfrac{{71}}{6}\)
D.\(I = 32\)
