Egg shells are made up Calcium Carbonate (CaCO3) ..
When it reacts with Hydrochloric Acid (HCl) it liberates Carbon Dioxide (CO2) ..Which turns lime water milky...
Hence chemical process is shown below :
 
CaCO3 + 2HCl -------> CaCl2 + HCl + CO2
 
Hence , HCl is the required solution which will react with crushed egg to produce CO2 and turns lime water milky.
 
Correct option :(B) :HCl.
