Correct answer
C18 molecules of ATP

Step-by-step explanation

Synthesis of glucose molecule in photosynthesis involves following reaction:

1 2 H 2 O + 1 2  NADP  + 18 ADP  ⟶ Light reaction 6 O 2 + 1 8  ATP + 1 2  NADPH

6 CO 2 + 1 2  NADPH + 1 8  ATP ⟶ Dark reaction C 6 H 1 2 O 6 + 1 2  NADP + 1 8  ADP + 6 H 2 O

6 CO 2 + 6 H 2 O ⟶ C 6 H 1 2 O 6 + 6 O 2
