Concept:
The *Mahapadana Sutta* of the *Digha Nikaya* lists the details of the past six Buddhas who preceded Gautama Buddha. Each Buddha is listed with their birthplace, parentage, and tree of enlightenment.
Step 1: Identifying the parentage of Vipassī Buddha.
Vipassī Buddha was the 19th Buddha of the 28 Buddhas and the first of the seven "Sapta-Tathagata." According to the Pali records, his father was King Bandhumān and his mother was Queen Bandhumatī. He was born in the city of Bandhumatī.
Step 2: Ruling out other options.
Option (4) Mahāprajāpatī and Suddhodana were the foster-mother/aunt and father of the historical Gautama Buddha, not Vipassī.
