Answer

Bhagwan Munisuvrata Swami, the 20th Tirthankar of the present Avasarpiṇī, is traditionally known as the son of:

• Father: King Sumitra
• Mother: Queen Padmavati

So, the correct pair is Sumitra and Padmavati.

Clarification

Priyankar and Manorama are not the traditionally accepted parents of Bhagwan Munisuvrata Swami in standard Jain tradition.

Takeaway

Bhagwan Munisuvrata Swami’s parents are remembered as King Sumitra and Queen Padmavati.
