CFAI Mock CorpFin-Nominal Discount rate

Hi the question asks about if you should adjust nominal discount rate to discount nominal cash flow, answer says you use nominal cashflow and dont need tool adjust for inflation, which i get

but then it says-inflation is already included in nominal discount rate, THAT i dont get, someone pls enlighten me

Real rates don’t include inflation; nominal rates do.

further proof i am going insane, thanks!

You’re welcome.
