The correct option is A 20
Given,
Amenda bought 32 bottles of cold drink each having 10 ounces of volume.
So,
Total volume =(32×10)=320 ounces.
Now,
Converting the total volume into pints.
We know,
1 cup =8 ounces
Or,
2 cups =16 ounces
Also,
2 cups =1 pint
⇒1 pint =16 ounces
So, for 320 ounces
Number of pints =32016=20 pints.
