A crate is lifted from the ground to a platform using two different hoist systems, System X and System Y. System X takes $\text{ seconds}$ to lift the crate. The useful work done by System X is $W$ , and the useful power developed is $P$ . System Y takes $\text{ seconds}$ to lift the identical crate to the same platform.

Which row in the table correctly describes the useful work done and the useful power developed by System Y?

	Useful work done by System Y	Useful power developed by System Y
A	$W$	less than $P$
B	$W$	more than $P$
C	more than $W$	less than $P$
D	more than $W$	more than $P$

Useful work done: $W$ ; Useful power developed: less than $P$

Useful work done: $W$ ; Useful power developed: more than $P$

Useful work done: more than $W$ ; Useful power developed: less than $P$

Useful work done: more than $W$ ; Useful power developed: more than $P$

Which row in the table correctly describes the useful work done and the useful power developed by System Y?

	Useful work done by System Y	Useful power developed by System Y
A	$W$	less than $P$
B	$W$	more than $P$
C	more than $W$	less than $P$
D	more than $W$	more than $P$

Useful work done: $W$ ; Useful power developed: less than $P$

Useful work done: $W$ ; Useful power developed: more than $P$

Useful work done: more than $W$ ; Useful power developed: less than $P$

Useful work done: more than $W$ ; Useful power developed: more than $P$
