The correct answer isC. In UiPath'sContext Groundingconfiguration, the“Number of results”setting directly affects how manychunks of indexed knowledgeare retrieved and passed to the LLM at runtime. These chunks come from preprocessed documents and are used to build thegrounding payload— the content added to the agent's prompt for context-aware generation.
By increasing the number of results:
The LLM has access tomore context, which can improve response quality if the added information is relevant.
However, it alsoincreases the token load, which can reduce prompt space or introduce irrelevant noise if poorly tuned.
Reducing the number of results leads tomore focused prompts, with only top-ranked relevant chunks (based oncosine similarity) included. This is crucial when using large indexes or when LLM context windows are limited.
Option A confuses this setting with similarity threshold tuning, which is a separate parameter.
Option B is false — the agent doesnot ignore contextunless context grounding is disabled.
Option D misrepresents the function — Orchestrator folder selection is unrelated to this retrieval setting.
In summary, the “Number of results” setting allows fine-tuning ofhow much supporting context is retrievedand passed to the model. It is a key control in optimizing performance, precision, and relevance of grounded agent responses.
