What word describes the officer's manner when asking to see the suitcase contents?

In this context, the word that describes the officer's manner when asking to see the suitcase contents should reflect a negative or unfriendly disposition. The chosen word suggests an approach that is not just neutral or positive but implies a degree of annoyance or harshness in their tone or body language, which is conveyed through the use of "unpleasantly." This term strongly indicates that the manner of speech used by the officer was not welcoming or agreeable.

The other options present varying degrees of positive or neutral behavior which would imply a more sociable or agreeable interaction, but they do not align with the implication of a critical or unfriendly attitude that comes across with "unpleasantly." When describing someone's manner in this specific situation, using a word that suggests negativity captures the essence of the officer's approach more accurately.
