LangChain - AgentsWhich of the following is the correct way to start defining a custom agent class in Langchain?Adef MyAgent():Bclass MyAgent(BaseAgent):Cagent = CustomAgent()Dclass MyAgent():Check Answer
Step-by-Step SolutionSolution:Step 1: Identify class inheritance patternCustom agents usually inherit from a base agent class to get core features.Step 2: Check syntax correctnessDefining a class with inheritance uses 'class ClassName(BaseClass):'.Final Answer:class MyAgent(BaseAgent): -> Option BQuick Check:Custom agent class syntax = class with inheritance [OK]Quick Trick: Custom agents inherit from base agent classes [OK]Common Mistakes:MISTAKESDefining agent as a functionNot inheriting from a base classAssigning agent instance instead of class
