The gravitational field is given by F = Gm/r^2, where G is the gravitational constant, m is the mass of the Earth, and r is the distance to the moon. Plugging in the values, we get F = (6.674 * 10^-11 N m^2 / kg^2) * (5.98 * 10^24 kg) / (3.85 * 10^8 m)^2 = 2.69 * 10^-3 N/kg. The force is toward the Earth, so the answer is A.
