ANSWER
D. and
Worked solution
Flux density is the field magnitude B. The area normal is perpendicular to the field, so . Zero flux through this orientation does not mean zero field.
Equivalent physically justified methods, alternative valid sketches and consistent units accepted.
Accept sensible significant figures and consistent rounding from stated constants.
