Choose the option with a correct u-substitution and antiderivative for the integral: ∫ 3 (8x + 1) cos(4x² + x) (sin(4x² + x))² dx
A
u = sin(4x² + x); du = cos(4x² + x)(8x + 1) dx; F(x) = (sin(4x² + x))³ + C
B
u = sin(4x² + x); du = cos(4x² + x)(8x + 1) dx; F(x) = (sin(4x² + x))² + C
C
u = cos(4x² + x); du = -sin(4x² + x)(8x + 1) dx; F(x) = (cos(4x² + x))³ + C
D
u = sin(4x² + x); du = sin(4x² + x)(8x + 1) dx; F(x) = (sin(4x² + x))³ + C
