As the rocket moves in the direction of force generated by fuel, therefore it is positive work. As the force of gravity acts in the direction opposite to the displacement. Therefore, it is negative work.

Explanation:
When a rocket rises up in the air, it is propelled by the force generated by the fuel. In order to understand the work done by the fuel and the force of gravity, we need to consider the definition of work.
Work: In physics, work is defined as the product of the force applied on an object and the displacement of the object in the direction of the force.
Now let's analyze the work done by the fuel and the force of gravity separately.
Work done by the fuel:
- The fuel generates a force that propels the rocket upwards.
- This force acts in the direction of the displacement (upwards) of the rocket.
- Therefore, the work done by the fuel is positive, as the force and displacement are in the same direction.
- The fuel is doing positive work on the rocket.
Work done by the force of gravity:
- The force of gravity acts downwards on the rocket.
- When the rocket rises, its displacement is in the opposite direction to the force of gravity.
- Therefore, the work done by the force of gravity is negative, as the force and displacement are in opposite directions.
- The force of gravity is doing negative work on the rocket.
Conclusion:
Based on the analysis above, we can conclude that the work done by the fuel is positive (as it propels the rocket upwards) and the work done by the force of gravity is negative (as it acts in the opposite direction to the displacement of the rocket). Therefore, the correct answer is option 'B': the fuel does positive work and the force of gravity does negative work.
