Answer:
Batch "B" more resistant to frost.
Step-by-step explanation:
The depression in freezing point is a colligative property. More the number of solute particles in a solution lesser its freezing point.
In Batch "A" we have taken 8.19 grams of a salt and in batch "B" 8.32 g of salt.
Assuming that same salt is being used the number of particles of salt in batch "B" will be more than batch "A".
Due to this batch "B" will show higher colligative property and will have more depression in freezing point making is more resistant to frost damage.
