Solution

The correct option is C 200 kJ
As it is mention in the that either the temperature is rising or not we will take it as constant then the heat produced will be
$H e a t p r o d u c e d = 50 \times 4 = 200 k J$
Hence 200kJ heat is produced when 4g of anhydrous solid is added to 50g of water.
