This key only opens one of the five cars — can you guess which one?

A mysterious key is found in a parking lot with five cars:

A: a luxurious black SUV

B: a shiny silver sedan

C: a bronze crossover

D: a blue hatchback

E: a powerful gray pickup

The key only opens one of the five cars.
When you press the unlock button, you hear a “beep” sound... but from the most unexpected direction.

When you follow the string from the key in the bottom left corner, the correct string leads to car D (the blue car). ✅

Answer: D
