Hi @RishiVC1,
For Beginner’s I would suggest you to first start with recording so that you will get a skeleton first.
This will help you understand which activities can be used under which options, buttons, combo box etc
In the above scenario you can use Select item activity to get the entire list from the drop down and on the basis of your criteria you can select the required option. You can also refer the link below :
