Which prefix indicates a strong tendency or attraction toward something?

The prefix “philia-” signifies an affinity or strong tendency toward something, often reflecting a love, attraction, or fondness for a particular subject or object. For example, terms like "anthrophilia," which refers to an attraction to humans, and "philanthropy," which describes love for humanity through charitable acts, illustrate the positive connotation associated with this prefix. This characteristic makes "philia-" the appropriate choice when referring to a strong tendency or attraction.

In contrast, "phobia-" indicates a fear or aversion to something, "sarco-" relates to flesh, and "poly-" denotes many or multiple. Each of these prefixes conveys entirely different meanings that do not align with the concept of attraction. Therefore, “philia-” is specifically associated with a favorable inclination, making it the correct answer in this context.
