Answer

The correct thermochemical equation for the complete combustion of glucose is represented by option A:

$C_6H_{12}O_6 + 6O_2 → 6CO_2 + 6H_2O$

with a ΔH of -2860 kJ mol⁻¹. This equation accurately reflects the complete oxidation of glucose into carbon dioxide and water, releasing energy in the process.
