Why does LangChain separate PromptTemplate from LLM components in its architecture?

ATo enforce strict typing on input variables

BTo allow flexible prompt design independent of the language model

CTo improve runtime performance by caching prompts

DTo enable multi-threaded execution of prompts

Step-by-Step Solution

Solution:

Step 1: Understand the roles of PromptTemplate and LLM
PromptTemplate defines how prompts are structured; LLM generates text from prompts.
Step 2: Reason why separation is beneficial
Separating them allows changing prompts without changing the model, enabling flexibility.
Final Answer:
To allow flexible prompt design independent of the language model -> Option B
Quick Check:
Separation = flexible prompt design [OK]
