Explanation

Dry ice (solid carbon dioxide) was first observed by French chemist Charles Thilorier in 1825 when he opened a pressurized container of liquid carbon dioxide and noticed the solid formation. This discovery was significant for understanding CO2's properties. 1734 is too early, 1892 and 1906 are much later dates.
