Find T, N, and B for the given space curve.r(t) = (6t sin t + 6cos t)i + (6t cos t - 6 sin t)j - 2k
A. T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j; B = -2k
B. T = (cos t)i + (sin t)j; N = (-sin t)i + (cos t)j; B = k
C. T = (cos t)i - (sin t)j; N = (-sin t)i - (cos t)j; B = -k
D. T = (-cos t)i - (sin t)j; N = (sin t)i - (cos t)j; B = -k
