The correct answer is C: Take cover under a desk or table.

• Rushing out of the building during an earthquake is dangerous as tremors can cause debris to fall and injure people. It is not a recommended safety measure.
• Holding an earthquake drill is good practice, but it is not a safety measure that can be followed during an actual earthquake.
• Taking cover under a desk or table is the correct safety measure. It provides protection from falling objects and reduces the risk of injury. Students should hold onto the desk or table legs to prevent it from moving during tremors, and stay underneath until the shaking stops.
• Going near windows during an earthquake is dangerous as glass panes can shatter and injure people.
