Explanation:

• Parivrajaka – Renunciant and Wanderer: This pairing is correct. A 'Parivrajaka' in the context of ancient Indian culture was someone who had renounced the worldly life and wandered from place to place, often in search of spiritual knowledge or enlightenment.

• Shramana – Priest with a high status: This pairing is incorrect. 'Shramana' refers to a seeker or ascetic who has renounced the worldly life, especially in the context of Jainism and Buddhism. Shramanas were not priests in the Vedic tradition, nor were they always associated with a high status. Instead, they often stood in contrast to the Brahminical tradition.

• Upasaka – Lay follower of Buddhism: This pairing is correct. An 'Upasaka' (male) or 'Upasika' (female) refers to a lay follower of Buddhism. They are devoted adherents but do not take monastic vows.
