Index fund and active fund

Is the 5 year CAGR showing for mutual fund schemes are after deducting the expanse ratio ? Or in reality the return will be lower based on expanse ratio?

For eg

If in coin.Zerodha

1- FUND A showing 5 Yr CAGR of 15% and expanse ratio 1%

2- FUND B showing 5 Yr CAGR of 15% and expense ratio of 0.5%

I should chose fund b or a ?

AFAIK NAV is declared after the expenses, so the returns are after the expenses.
