Hi,
You are talking about product listing.
A product listing is a listing of product and it's not the product page.
Product options are just displayed on the product page because there is a lot of information to display, some complex javascript sometimes in order to manage the dynamic price or "linked options" and "linked variants". That's why we do not display the option selection in the product listing.
But the product page, which is the page of the product, works in one single step.
As Xavier explained, if you want to integrate the option selection in the product listing, it would require some develpment and PHP skills.
