Answer: (B)

Verified step by step guidance

1. Understand the primary safety concerns in a chemistry laboratory, which include exposure to hazardous chemicals through spills, splashes, or contact with skin.
2. Recognize that wearing long sleeves provides a physical barrier that helps protect the skin from direct contact with harmful chemicals, reducing the risk of burns, irritation, or absorption of toxic substances.
3. Note that preventing chemical exposure is more critical than concerns like odor absorption or contamination of equipment, which are less effectively addressed by clothing alone.
4. Consider that long sleeves do not necessarily improve dexterity; in fact, they might sometimes restrict movement, so this is not a primary reason for wearing them.
5. Conclude that the main reason for wearing long sleeves in the lab is to enhance personal safety by minimizing skin exposure to chemical hazards.
