The correct answer is - larger than the front line; Ponzo illusion

Explanation:

The Italian psychologist Mario Ponzo in 1913 presented an optical illusion that is called the Ponzo illusion. According to this illusion, we perceive the size of an object based on the background of the particular object.

He demonstrated this illusion by drawing two identical lines across a pair of converging line that makes it look like a train track and it appears that the back line draw is larger than the front line.

In the given case the background appears to be larger than the front line, however, both lines are identical but give Ponzo illusion.
