The item in "The Binding of Isaac" that reveals secret and super-secret room locations is A) Holy Mantle.
Step-by-step explanation:
In the game "The Binding of Isaac," the item that allows players to reveal the locations of secret and super-secret rooms upon unlocking it by donating 10 pennies to the Shop is: A) Holy Mantle. Holy Mantle is a defensive item in the game that provides a shield for the player, absorbing the first instance of damage on each room. However, it appears that there might be a confusion in the question, as revealing secret rooms is usually associated with the item "X-Ray Vision" rather than Holy Mantle. Holy Mantle is more recognized for its protective capabilities rather than revealing secret room locations. Nevertheless, based on the options provided, Holy Mantle is the closest match.
