The guess of 1 was marked incorrect
Homework Answers
Here we are given that the vector a and b are orthogonal it implies that both are perpendicular to each other and the angle between both of them is 90 degree so dot product of a and b is abcos(theta) where they is 90 degree so we know cos90 is zero and thus option is A that is zero
