But the answer is A. 2ATP because After glycolysis only 2 ATP is created, the rest come from Kreb's cycle and the oxidative phosphorylation.

In the glycolysis we have investing phase and gain phase. In the investing phase we use 2 ATP and in the gain phase we get 4 ATP back.. so the net ATP gained is 2 ATP.
