Who among the following friends of Everyman, the main protagonist of the best-known morality play, Everyman, stays with him when he leaves the world to face Death?

The correct option is Good Deeds.

In the late 15th-century English morality play Everyman, the protagonist Everyman is summoned by Death to give an account of his life before God. As he prepares for this journey, he realizes he is unprepared and seeks companions to accompany him to help make his ledger of accounts favorable.

Everyman approaches various personified allegorical figures that he cherished in life, including Fellowship, Kindred, Cousin, and Goods (Wealth), all of whom refuse to go with him. He then turns to his physical attributes and mental qualities, such as Beauty, Strength, Discretion, and Five Wits. While they initially promise to stand by him, they ultimately abandon him one by one as he reaches the grave, realizing they cannot cross the threshold of death.

Knowledge acts as a guide, leading Everyman to confession and helping him prepare, but Knowledge also explains that she cannot go into the grave with him. Only Good Deeds, who was initially weak and bound to the ground by Everyman's sins, is restored to health through Everyman's repentance and penance. Because of this, Good Deeds is the sole companion who stays with Everyman through the final journey, descending into the grave with him to speak for him before the divine tribunal.
