The correct option is B decreases
The amount of water sent out through urine depends on the water required by our body. During hot days, our body requires a lot of water. So, even if we drink a lot of water, the amount of urine produced is less. During cold days, our body sends out a lot of water, so the amount of urine produced is more. Approximately 1 - 1.5 L of urine is produced per day.
