Answer :
The most likely option is 50 degrees Celsius. Option A is correct.
We can examine the possibilities:
- a) 50 degrees Celsius: Given how many people prefer their hot beverages at this temperature, this is a possibility.
- b) 100 degrees Celsius: This is the temperature at which water boils and is too hot to drink. It is improbable that hot chocolate will be offered cold.
- c) 0 degrees Celsius: This is water's freezing point, and it has nothing to do with a hot chocolate cup.
- d) 25 degrees Celsius: This is not the usual temperature for hot chocolate and is usually regarded as somewhat lukewarm.
So, the most likely option is 50 degrees Celsius,
