Question

which phrase has the most negative connotation?
an abnormal result
an atypical result
an unusual result

Explanation:

To determine the phrase with the most negative connotation, we analyze the meanings: "abnormal" implies deviation from what is normal/healthy, often with negative implications (e.g., in medical or general contexts, it suggests something wrong). "Atypical" means not typical but can be neutral or slightly positive (e.g., a unique finding). "Unusual" just means not common, with a more neutral tone. So "an abnormal result" has the strongest negative connotation.

Answer:

A. an abnormal result
