Hello Samid,
First of all check installation guide and follow the steps of preperation, installation and post installation steps.
If you are installing the system on one host choose standart system and continue.
If yıu are distributing db and sap on different hosts choose the one you selected on picture.
If you are installing the system on a high available system then select the 3rd option which is High-Availability System.
As I mentioned above follow the related steps on installation guide.
Regards,
