B. The water must be heated before mixing.
C. The acid must be heated before mixing.
D. The acid must be slowly added to the water.
Answer: Option D
Solution (By JKSSB Mock Tests Team)
Mixing a strong acid with water is an intensely exothermic process that releases significant heat. Acid must always be poured slowly into a larger volume of water to dissipate the heat safely, whereas adding water directly to acid can cause dangerous, explosive boiling and splashing.
