What travel adaptor for Switzerland?

So, I will be traveling to Switzerland from Asia and will require buying a travel adapter for the region.
What travel adapter form below will I require for Switzerland? I have listed some below. Can I use the adaptor that can be used in Germany too (Picture B)?



A is okay for here but...B looks like an adapter I have. It works in a number of countries and will be fine here in Switzerland. If it's one you already have, why buy something else?

Thank you for the answer. ^^ I won't get the other one. It's rare and super pricey in my home-country.
