According to the Theravada commentarial account, which pair identifies the council held shortly after the Buddha’s passing and its venue?

Explanation

First Buddhist Council - Rajagriha (Rajagaha). The Theravada commentarial account describes elders led by Mahakassapa selecting Rajagaha for a council to recite the Dhamma and Vinaya after the Buddha’s passing. This is a tradition-specific account; an exact BCE year is not needed to identify the council and venue.
