To calculate the gravitational force of attraction between two objects, you can use the formula:

F = (G * m1 * m2) / r^2

Where:
F is the gravitational force
G is the universal gravitational constant (6.7 × 10^-11 m³/(kg.s²))
m1 and m2 are the masses of the two objects (2.0 kg each in this case)
r is the distance between the centers of the two objects (2.0 m)

Plugging in the values:

F = (6.7 × 10^-11 * 2.0 * 2.0) / (2.0)^2
F = (6.7 × 10^-11 * 4) / 4
F = 26.8 × 10^-11 / 4
F = 6.7 × 10^-11 N

Therefore, the gravitational force of attraction between the two spheres is 6.7 × 10^-11 N. So, the correct answer is A. 6.7 × 10^-11 N.
