Systems in nature tend to undergo changes explain your answer.
1. lower energy and lower entropy.
2. lower energy and higher entropy.
3. higher energy and lower entropy .
4. higher energy and higher entropy.

The correct answer is option 2. Systems, by nature, tend to undergo changes toward higher entropy and lower energy since this is the state where they are most stable. Entropy is the degree of disorderliness of a substance. Systems tend to go to higher disorder since systems always tend to change which can be linked to disorder and is inevitable.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
