Business Casual Outfits are outfits that are relatively casual thus suits are not required in this ensemble.
The modern business casual look can be a sports jacket as seen on the pictures above, a casual shirt , it doesn’t have to be white dress shirt, it can be a polo or checked shirt with patterns and then jeans or commuter pants or chinos and then shoes , a gentleman can go with a loafer or any casual shoe such as blue swade or boots but not sneakers or black formal shoe since those are different elements altogether hence it will contradict the look
