Which word best describes the author’s tone in the passage about antibiotic resistance?

Read the passage: Antibiotics have transformed medicine, turning once deadly infections into conditions that can be cured in a few days. Yet their success carries a hidden danger. Each time antibiotics are used, bacteria that happen to survive can multiply and pass on their resistance. Taking these medicines for viral illnesses such as colds, where they have no effect, or stopping a course early without medical advice, gives resistant bacteria more chances to spread. Already, some infections that were easily treated a generation ago now require stronger drugs, and a few respond to almost none. Unless doctors, patients and farmers use antibiotics more carefully, we risk returning to a time when a simple cut or a routine operation could once again be life-threatening.

Correct answer A. Concerned

Explanation

The author warns of a 'hidden danger' and of simple cuts becoming life-threatening again, which shows a concerned, cautionary tone rather than humour or indifference.
