Please help! I think the answer is C, but I\'m not sure.

If one of the normal vectors to an interface is n^wedge = 1/5 (4x^wedge - 3z^wedge) and the magnetic field just below the interface is H_rightarrow_1 = 10x^wedge + 2y^wedge + 8z^wedge, what is the vector part of H_rightarow_1 tangential to the interface? H_rightarrow_1t = [(10 - 256/25)x^wedge + 2y^wedge + (8 -192/25)z^wedge] None of the others H_rightarrow_1t = [(10 - 64/25)x^wedge + 2y^wedge + (8 + 48/25)z^wedge] H_rightarrow_1t = [-10/25x^wedge + 2 y^wedge - 1/5z^wedge] H_rightarrow_1t = [(10 - 260/25)x^wedge + 2y^wedge + (8 -195/25)z^wedge]
