Verified step by step guidance

1. Understand that the question is about laboratory safety and technique rather than a calculation or chemical concept.
2. Recall that when handling chemicals, especially acids, there is a common safety mnemonic to ensure proper pouring technique.
3. The word 'Acid' is often used to remind students to pour acid carefully, typically by pouring acid into water to prevent splashing and exothermic reactions.
4. Other options like 'Label' remind students to check chemical labels, and 'Waft' is a technique to safely smell chemicals, but neither directly relates to pouring technique.
5. Therefore, the correct word associated with the correct pouring technique in the lab is 'Acid', emphasizing careful handling.
