LangChain - Chains and LCEL

What is the main purpose of a SequentialChain in Langchain?

ATo create a single chain that never passes outputs

BTo run multiple chains all at the same time independently

CTo run multiple chains one after another, passing outputs as inputs

DTo stop chains from running automatically

Step-by-Step Solution

Solution:

Step 1: Understand SequentialChain behavior
A SequentialChain runs chains in order, passing output from one to the next.
Step 2: Compare options to this behavior
Only To run multiple chains one after another, passing outputs as inputs describes this step-by-step passing of outputs between chains.
Final Answer:
To run multiple chains one after another, passing outputs as inputs -> Option C
Quick Check:
SequentialChain = run chains sequentially with output passing [OK]

Quick Trick: Sequential means one after another with output passing [OK]
