Reading 17 EOC Q12 Net income under different accounting method

Reading 17 EOC Q12 says the net income is not affected by the accounting method used to account for active investments in other companies.

But I think the acquisition method would account for the entire net income of the company being invested in while the proportionate method and equity method would only account for a portion of the net income.

Could anyone please clarify this?

In the acquisition method you’d subtract the minority interest in the subsidiary’s income; the results are the same under all three methods.
