(C) Given: Diameter of the sphere $(d)$ = $14 \, cm$.Radius of the sphere $(r)$ = $d / 2 = 14 / 2 = 7 \, cm$.The formula for the surface area of a sphere is $A = 4 \pi r^2$.Substituting the values: $A = 4 \times (22 / 7) \times (7)^2$.$A = 4 \times (22 / 7) \times 49$.$A = 4 \times 22 \times 7$.$A = 88 \times 7 = 616 \, cm^2$.
