Answer ::

12H2O + 12 NADP + 18 ADP → 6O2 + 18 ATP + 12 NADPH ( light reaction)
6CO2 + 12 NADPH + 18 ATP → C6H12O6 + 12 NADP + 18 ADP + 6H2O (dark reaction)
6CO2 + 6H2O → C6H12O6 + 6O2 (Net reaction)
18 molecules of ATP is involved in the synthesis of each molecule of glucose in photosynthesis.
Hence option (1) is the answer.
