Final answer:
A friend is someone you can see without needing a specific reason, an acquaintance is seen only when there's a specific reason, and a crush is someone you find excuses to see due to romantic interest. The correct answer to the question is C) Friends are people seen for no particular reason.
Step-by-step explanation:
The distinction between a friend, an acquaintance, and a crush can fundamentally be understood through the proximity and frequency of interaction one has with each. A friend is someone that you can see for no particular reason, indicating a relationship that is comfortable and consistent enough that it doesn’t require a special occasion or purpose for meeting up. On the other hand, an acquaintance is someone you do not see unless there's a specific reason to do so. These are people you might say hello to at school or in the grocery store but do not pursue deeper social interactions with outside those contexts.
A crush, however, is someone that you find excuses to be around because of a romantic or deep personal interest you have in them. This differentiates a crush from friends and acquaintances because it involves an intentional effort to create opportunities for interaction, often driven by a desire to form a closer relationship or explore romantic possibilities.
Considering these definitions, the correct answer to what distinguishes a friend from an acquaintance and a crush is C) Friends are people seen for no particular reason.
