K Suppose u and v are differentiable functions at t = x with u(n) = (0,5, - 3) , u'() = (0,2, -4), v(x) = (0,2,4), and v'(x) = (-5,1, - 2) . Use this information to evaluate di (uxv ) It = x Select the correct choice below and fill in the answer box(es) to complete your choice. O A. The value of - (uxv) d is the scalar It = x O B. The value of d at (uxv ) is the vector
