The question is a bit ambiguous. It seems to be asking about the heat of reaction for the formation of two moles of water. However, the phrasing "composition two moles water" isn't a standard chemical term.

Here's a breakdown of what we can understand:

* Formation of Water: The standard reaction for the formation of water is:

```

2H₂(g) + O₂(g) → 2H₂O(l)

```

* Heat of Reaction (Enthalpy Change): The heat of reaction, also known as enthalpy change (ΔH), tells us how much heat is released or absorbed during a reaction. For the formation of water, the standard enthalpy change (ΔH°) is -571.6 kJ/mol. This means that 571.6 kJ of heat are released when two moles of water are formed from their elements in their standard states.

Therefore, the correct heat of reaction for the formation of two moles of water is -571.6 kJ.

Note: The negative sign indicates that the reaction is exothermic, meaning heat is released.
