Aclient = AsyncMongoClient('mongodb://localhost:27017')
Bclient = MotorClient('mongodb://localhost:27017')
Cclient = MongoClient('mongodb://localhost:27017')
Dclient = AsyncIOMotorClient('mongodb://localhost:27017')
Step-by-Step Solution
Solution:

  1. Step 1: Identify the correct Motor client class

    The Motor library provides AsyncIOMotorClient for asynchronous MongoDB connections.

  3. Final Answer:

    client = AsyncIOMotorClient('mongodb://localhost:27017') -> Option D

  4. Quick Check:

    Motor uses AsyncIOMotorClient for async connections [OK]
Quick Trick: Use AsyncIOMotorClient for async MongoDB connections [OK]
Common Mistakes:
MISTAKES
  • Using synchronous MongoClient instead of AsyncIOMotorClient
  • Using incorrect class names like MotorClient or AsyncMongoClient
