As you will not be staying more than 3 months you will need a short stay (Schengen) visa. These visas are also called VKV (acronym for Visum Kort Verblijf in Dutch) or Type C visas and cost β¬60.
Because you are an Indian citizen your internship provider also needs to arrange a work permit for you (Tewerkstellingsvergunning, or TWV in Dutch).
