Find T, N, and B for the given space curve.
-r(t) = (8t sin t + 8cos t) i + (8t cos t - 8 sin t) j - 5k
A) T = (-cos t) i - (sin t) j; N = (sin t) i - (cos t) j; B = -5k
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
