Dear student,
 

A china dish weighs 25 g when empty. When a saturated solution of potassium chloride is poured into it at 40o C, the weight of the dish is 63 g. 


Hence, the weight of KCl solution is 63−25=38 g.

When the solution is totally evaporated, the chine dish along with the crystals weighs 40 g. 

The weight of solid KCl is 40−25=15 g.
The solubility of potassium chloride at 40oC= 15/38​×100 =39.5 g  KCl / 100 g solution. 
Hence, option (C) is the correct answer.

Regards
