The correct option is B 7 litre 750 ml
Given:
Capacity of Bucket to hold water = 25 litre
Water in the bucket = 17 litres 250 ml
Space remaing in the bucket = Amount of water bucket can still hold
Amount of water bucket can still hold = 25 litre - 17 litre 250 ml
litre ml25 000− 17 250–––––––––––––––7 750
i.e, Bucket can hold 7 litre 750 ml more water.
