print(embedding['moon'])

ABecause 'moon' key is not in the embedding dictionary

BBecause the vector values are floats

CBecause the dictionary is empty

DBecause print() cannot print lists

Step-by-Step Solution

Solution:

Step 1: Check dictionary keys
embedding contains only 'sun' key, not 'moon'.
Step 2: Understand KeyError cause
Accessing a missing key with [] raises KeyError.
Final Answer:
Because 'moon' key is not in the embedding dictionary -> Option A
Quick Check:
Missing key access = KeyError [OK]
