The correct answer is option A. When hot water is sprinkled on a thick glass, the sudden temperature change causes the glass to expand rapidly. Glass is a poor conductor of heat, so uneven heating can occur, leading to uneven expansion. This uneven expansion creates stress within the glass, which can exceed its tensile strength, ultimately causing it to fracture. Therefore, the sudden expansion of the glass due to the hot water is the primary reason for its breakage in this scenario. Options B, C, and D are incorrect because the breakage is primarily caused by thermal expansion rather than compression, water evaporation, or chemical reaction with the glass.
