An individual produced $1.75\,\text{dm}^3$ of urine on a cool day. What would happen to the volume and concentration of the urine on a hot day, assuming the fluid intake stays the same as on the cool day?
- Avolume increases; concentration decreases
- Bvolume increases; concentration increases
- Cvolume decreases; concentration decreases
- Dvolume decreases; concentration increases
