What is the DataWeave expression to log the Content-Type header using a Logger component?

Answer options

• A. #["Content-Type: " ++ attributes.headers.'content-type']
• B. #["Content-Type: " ++ headers.'content-type']
• C. #["Content-Type: " + headers.'content-type']
• D. #["Content-Type: " + attributes.headers.'content-type']

Correct answer: A

Explanation

The correct answer is A because it correctly references the 'content-type' header within the 'attributes' object, which is essential for logging the header properly. Option B is incorrect as it uses 'headers' instead of 'attributes', while options C and D incorrectly use a different concatenation operator which may lead to unexpected results.
