How do you correctly instantiate a PydanticOutputParser for a Pydantic model named Order?

A<code>parser = PydanticOutputParser(model=Order)</code>

B<code>parser = PydanticOutputParser(pydantic_object=Order)</code>

C<code>parser = PydanticOutputParser(Order)</code>

D<code>parser = PydanticOutputParser(pydantic_model=Order)</code>

Step-by-Step Solution

Solution:

Step 1: Recall the correct parameter name
The PydanticOutputParser expects the Pydantic model to be passed via the parameter named model.
Step 2: Review the options
parser = PydanticOutputParser(model=Order) uses the correct parameter name and syntax. Options A, C, and D use incorrect parameter names or omit the parameter name.
Final Answer:
parser = PydanticOutputParser(model=Order) -> Option A
Quick Check:
Use model parameter for model [OK]

Quick Trick: Use model=ModelName when creating parser [OK]
