Answer:
B. Helium-filled balloons consume a resource that could be better used.
Explanation:
In an age where scarcity is a rather common and serious phenomenon, better allocation of resources is highly necessary. This is more true for non-renewable resources, such as, helium, which cannot be recovered back. For this reason, helium could be used in something more productive and useful instead of balloons. A better allocation of resources also helps in saving money.
