Solution

The correct option is B None
Magnitude of magnetic field $B = 2 T$
Area $A = 1.5 m^{2}$
Since the area is perpendicular to the magnetic field, so angle between the area vector and the magnetic field $θ = 0^{o}$
Magnetic flux passing through the surface $ϕ = B A cos θ$
$⟹ ϕ = 2 \times 1.5 \times cos 0^{o} = 3 W b$
