The biggest planet in the universe has not been discovered yet. However, of the three above, Jupiter is the largest.
I'm not sure exactly, but I believe that a hydrogen planet 20 times Jupiter's mass would be the maximum size of a gaseous planet before it would begin nuclear fusion and become a star.

Jupiter is the largest planet in our solar system. Not all the planets in the Universe have been discovered, so we don't know which one is the largest. Next time ask a better question, and you'll get a better answer.

I found this question kinda silly :)
I'm almost completely certain that Jupiter cannot be the largest planet in the universe. If you look at our sun in comparison to W Cephai, its just astonishing.

No one knows the largest in the universe, but the largest so far discovered is probably "HAT-P-1b, an extrasolar planet orbiting the Sunlike star ADS 16402 B. It is located 450 light years away from Earth in the constellation Lacerta. As of 2006, HAT-P-1b has the largest radius and lowest density of any known extrasolar planet. It also has the name Krais."

The universe is a very large place, and we have no idea how many planets it contains (probably several gazillion). Your question makes no sense.
You probably mean largest in our solar system, which is an insignificant part of the universe. If you can't tell the difference, you don't need the answer.

The entire universe? How the heck would we know?
We don't even have a clear difinition of a planet yet.
Jupiter the biggest planet in our solar system. None of the above is the biggest planet in the universe.
