Solution

The correct option is B $4200 J / k g /^{\circ} C$
The specific heat capacity of water is $4200 J / k g /^{\circ} C$ . Specific heat is the heat required to raise the temperature of $1 k g$ of a substance by $1^{\circ} C$ . Specific heat is the value that expresses the proportion between heat, mass and temperature slide for a certain substance.
