The liquid in question is most likely D) pure water. Here's why:

1. Anhydrous copper sulfate is a white powder that turns blue when it comes into contact with water. This is because it absorbs water and becomes hydrated copper sulfate, which is blue. This suggests that the liquid is water or contains water.

2. The boiling point of the liquid is given as 103°C. This is very close to the boiling point of pure water, which is 100°C at sea level.

3. The other options (alcohol, petrol, and salt solution) can be ruled out. Alcohol and petrol do not turn anhydrous copper sulfate blue, and they have different boiling points. A salt solution would turn anhydrous copper sulfate blue, but it would have a higher boiling point due to the presence of dissolved salt.

Therefore, the most likely identity of the liquid is pure water.
