(C) The magnetic flux $\Phi$ linked with a surface is given by the formula $\Phi = B A \cos(	heta)$,where $B$ is the magnetic field,$A$ is the area of the surface,and $	heta$ is the angle between the magnetic field vector and the area vector (normal to the surface).When the surface of the sheet is parallel to the magnetic field,the normal to the surface makes an angle of $90^{\circ}$ with the magnetic field lines.Therefore,$	heta = 90^{\circ}$.Substituting this into the formula: $\Phi = B A \cos(90^{\circ})$.Since $\cos(90^{\circ}) = 0$,the magnetic flux $\Phi = 0$.
