The checked answer is my click mistake..

Why is the equation from the previous step satised? 0 A. The components of n-(t) are negative reciprocals of the components of t). so the dot product is 1. O B. The components of n-(t) are negative reciprocals of the components of T, so the dot product is 1. O C. The sum of the components of v(t) is the negative of T, so the dot product is 0. O D. The components of mu are the components of v(t} with the order swapped and the sign of one changed, so the dot product is O. ammun- cN=(_Di+(_Di
