A uniform electric field is directed along the positive y axis. The magnitude of the electric field is 5.0 $\times$ 10⁶ N/C. The electric flux through a surface whose area is 400.0 cm² and intersects the x-z plane at a 60° angle is

A) zero.
B) 1.0 $\times$ 10⁵ N.m²/C.
C) 1.7 $\times$ 10⁵ N.m²/C.
D) 1.7 $\times$ 10⁶ N.m²/C.
