Gauss's Law: a Charge of 1

Gauss's law: A charge of 1.0 × 10^-6 μC is located inside a sphere, 1.25 cm from its center. What is the electric flux through the sphere due to this charge? (ε₀ = 8.85 × 10^-12 C²/N ∙ m²)

A) 0.11 N ∙ m²/C
B) 8.9 N ∙ m²/C
C) 0.028π N ∙ m²/C
D) It cannot be determined without knowing the radius of the sphere.
