Impact on Net income of equity method and acquisition method

CFA Level II FRA
#1

Question 12 practice problem, reading 16, FRA curriculum Level 2.

Why does the answer key say “net income is not effected by the accounting method used to account for active investment in other companies”?

Could someone please help me clarify this?

Thanks.

Net income is the same for equity method and consolidation, therefore it is not affected by accounting choice.

passive investment would change though.
