A software engineer developed an AWS Lambda function in Node.js to do some CPU-intensive data processing. With the default settings, the Lambda function takes about 5 minutes to complete.
Which approach should a developer take to increase the speed of completion?

A. Instead of using Node.js. rewrite the Lambda function using Python.
B. Instead of packaging the libraries in the ZIP file with the function, move them to a Lambda layer and use the layer with the function.
C. Allocate the maximum available CPU units to the function.
D. Increase the available memory to the function.
