Neptune takes the longest as it is the farthest away.
Neptune.
Technically, since Pluto is no longer a planet, but a dwarf planet, Uranus is the planet that takes the longest to orbit the sun.
If you still consider Pluto to be a planet, then the answer is Pluto, which completes one revolution around the sun in 248 years. If you agree with the downgrading of Pluto to something less than a full-fledged planet, then the answer is Neptune. The general rule is: The farther a planet is from the sun on the average, the longer it takes to complete its orbital revolution.
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total.
Mercury is the shortest and Neptune is the longest

If you mean revolution on it axis (spin/day length) rather than orbital period, then the answer is the planet Mercury, where time between sunrises is roughly 176 Earth days.
"Revolution" means orbiting around another body. A year is the time for a planet to complete one orbit around the Sun.
Pluto has the longest REVOLUTION period Venus has the longest ROTATION period
