Step 1: Identify the components of vectors A and B. Given vectors are: A = 3i + 4j - k B = -2i + 3j + k The components are: For A: A_x = 3, A_y = 4, A_z = -1 For B: B_x = -2, B_y = 3, B_z = 1 Step 2: Calculate the dot product A · B. The dot product of two vectors A = A_x i + A_y j + A_z k and B = B_x i + B_y j + B_z k is given by: A · B = A_x B_x + A_y B_y + A_z B_z Substitute the components: A · B = (3)(-2) + (4)(3) + (-1)(1) A · B = -6 + 12 - 1 A · B = 6 - 1 A · B = 5 The correct option is A) 5.
