One quart is equal to

Solution (By Examveda Team)

One quart is a unit of volume measurement in the US customary and imperial systems.

Option A: 250 ml

250 ml is incorrect as it is much smaller than a quart.

Option B: 500 ml

500 ml is half of a liter and also less than a quart.

Option C: 750 ml

750 ml is still less than a quart and is commonly used as a standard bottle size for wine.

Option D: 1000 ml

1000 ml is equivalent to 1 liter, which is very close to the volume of one quart (1 US quart ≈ 946 ml, 1 UK quart ≈ 1136 ml). Thus, 1000 ml is generally accepted as equivalent to one quart in practical terms.

Conclusion:

One quart is approximately equal to 1000 ml, making Option D the correct answer.
