Correct answer
d
the crane's capacity is 10 t or 20 t depending on the number of supporting rope parts
udźwig suwnicy w zależności od ilości pasm liny nośnej wynosi 10 t lub 20 t

The crane has two hoisting mechanisms (mechanizmy podnoszenia), each rated at 10 t, which can operate simultaneously. The marking does not describe rope reeving.
