According to the image, we can say that to form an ice cream unit you need 1 scoop of ice cream, 1 cone, and 1 cherry. In other words, the ratio between all the reactants is 1 to 1. Therefore, the limiting reactant will be the one with the least number of units.
If we count the amount of each of the reactants we have:
• 10 scoops of ice cream
,
• 7 cones
,
• 12 cherries
In less quantity are the cones, that is to say, that at most we can assemble 7 ice creams. Therefore, the limiting reactant will be the cone.
Answer: (B) Cone
