Final answer:
Peers most likely influence food choices, especially among the younger population, who often make decisions based on the desire to fit in with their social groups.
Step-by-step explanation:
The most common influencer of food choices, particularly among younger individuals, is D. Peers. When considering the dynamics of influence, peers often play a significant role in shaping preferences and behaviors, including dietary habits.
This is because as individuals, especially teenagers and young adults, spend considerable time with peers, the natural desire to fit in and be accepted can impact various choices, including where to shop, eat out, or grab a cup of coffee. This also aligns with the concept that peers can be agents of socialization, impacting not just immediate choices but potential long-term habits.
