In which illusion do the subjects typically report that the horizontal line closer to the origin of the diagonals is longer than the one away from the origin?

Ponzo illusion

Explanation:

The Ponzo illusion is a geometrical optical illusion that was first demonstrated by the Italian psychologist Mario Ponzo in 1911. He suggested that the human mind judges an object's size based on its background. He showed this by drawing two identical lines across a pair of converging lines, similar to railway tracks.
