{'gravitational force': [0, 0, 0, 6], 'correct value': [0, 0, 0, 3], 'earth': [0, 1, 1, 1], 'mass': [0, 0, 2, 3], 'kg': [0, 1, 9, 24]}

The gravitational force of the Earth acting on a body is given by the equation F = mg, where F is the gravitational force, m is the mass of the body, and g is the acceleration due to gravity.

In this question, the mass of the body is given as 1 kg. The value of g, the acceleration due to gravity, is approximately 9.8 m/s^2.

Let`s dissect each option to better understand them:

Option 1: The value of 8.9 N is less than the correct value.

Option 2: The value of 9.8 N aligns with the correct value of the gravitational force. This option is the correct answer.

Option 3: The value of 89 N is significantly higher than the correct value.

Option 4: The value of 98 N is also significantly higher than the correct value.

Therefore, the correct value of the gravitational force of the Earth acting on a body of mass 1 kg is 9.8 N.
