The sentence "The tears ran --- her face" is seeking a preposition that accurately describes the movement of tears in relation to the face. Among the options provided, "down" is the most appropriate choice.

When we talk about tears being shed, they typically flow downward due to gravity. The phrase "ran down her face" vividly illustrates this natural motion, creating a clear and direct visual of tears tracing a path down the skin. This expression is commonly used in English to evoke a sense of sadness or emotional release, making it not just grammatically correct but also contextually fitting.

On the other hand, the other prepositions do not convey the correct meaning. "In" suggests an inward motion, which does not appropriately describe tears, while "on" implies a static position rather than movement. "At" is grammatically incorrect in this context as it does not indicate directionality. Thus, "down" is not only the correct option but also the most emotionally resonant choice for conveying the imagery of tears falling from the face.
