Answer:

Answer is option (c)

Explanation:

Answer 2

"c- Zero work done"

Explanation:

Zero work is done when the removal of a body is zero or opposite (θ=900,cosθ=0) to the bearing of power applied, then, at that point, work done is zero.

Examples:

The power acts a descending way,

At the point when we hold an item and walk,

At the point when removal works the forward way.

On the off chance that you push a divider, it doesn't move there's no work done.

Resting for a long time is likewise an occurrence of not doing work.
