Change font on product page drop-down menu

Hi guys!

Please help me change the font on the product page, there should be a different font in the drop-down menu "size" and "paper". And also whether it is possible to increase this font so that it is the size of the price.

How do I change the font of the menu itself?

The rest code is here:
