Option B is the best solution to meet the requirements of the developer with the least possible change to the application code. By including the SDK in the Lambda function, the developer can use the SDK to upload the file to S3 without making significant changes to the application code. Option C is not recommended because using the SDK that is installed in the Lambda environment could lead to version conflicts and unexpected behavior if the SDK version in the environment is different from the version used by the developer.

Reason why it's not B: https://docs.aws.amazon.com/lambda/latest/dg/lambda-python.html You can run Python code in AWS Lambda. Lambda provides runtimes for Python that run your code to process events. Your code runs in an environment that includes the SDK for Python (Boto3), with credentials from an AWS Identity and Access Management (IAM) role that you manage.

is also not the best choice since it requires the developer to include the SDK for Python in the application code, which may increase the size of the deployment package and the time it takes to deploy the function.

Selected Answer: C

it's probably still C because even with A you need a presigned url though i would mention that boto is ending support for python so this question may not be so relevant. though you probably can use the older versions of python https://github.com/boto/boto3 "On 2022-05-30, support for Python 3.6 was ended. This follows the Python Software Foundation end of support for the runtime which occurred on 2021-12-23. For more information, see this blog post."

my copy paste didn't work, here's the quote i was going for "Because the boto3 module is already available in the AWS Lambda Python runtimes, don’t bother including boto3 and its dependency botocore in your Lambda deployment zip file."
