Let \( f^{\prime}(x)=\frac{192 x^{3}}{2+\sin ^{4} \pi x} \) for all \( x \in R \) with \( f\left(\frac{1}{2}\right)=0 \). If \( m \leq \int_{1 / 2}^{1} f(x) d x \leq M \), then the possible values of \( m \) and \( M \)
\( P \)
W are
(2015 Adv.)
(a) \( m=13, M=24 \)
(b) \( m=\frac{1}{4}, M=\frac{1}{2} \)
(c) \( m=-11, M=0 \)
(d) \( m=1, M=12 \)
