Which option shows an unsafe work practice?

Correct answer: Using sharp tools without care

An unsafe work practice is one that unnecessarily increases the chance of injury, illness or damage. Sharp tools can cut the body or cause other accidents if they are used carelessly. Safe work requires attention, proper handling, suitable protective equipment and following instructions. Safety is important in domestic work, laboratories, workshops and every other workplace.

Option C is correct because using a sharp tool without care ignores a basic safety precaution. Wearing gloves, reading instructions and keeping the workplace clean generally reduce risks, so options A, B and D describe safer behaviour. The question asks for the unsafe practice, not simply an action related to tools. The phrase without care is the important clue.
