Heating of sugar solution is a chemical change. State whether the statement is true or false

Solution
The correct option is A True
When sugar is dissolved in water, a small amount of heat is produced, a "heat of solution." This heat arises from the chemical reaction between the solute (the sugar) and the solvent (the water). The sugar crystals of sugar breaks down in the molecules and remain suspended in the water. In high school, the answer is physical change: no bonds between atoms are made or broken, so it is not considered chemical. In reality, things are more complicated, and non-covalent bonds between water and sugar can be considered a chemical change too. And even further, many sugars can open and close rings when in water solutions.
