Its Uranus...
A planet rotates on its axis, an imaginary line that runs from its North Pole to its South Pole. This rotation determines the length of a day on the planet.
Pretty much every planet has an axis, because an axis is what a planet rotates around. Any planet that rotates has an axis, and pretty much every planet known rotates.
No planet does this. You probably mean the planet that ROTATES on its axis in an east to west direction. The answer is Venus. Uranus also does this, but with an extreme axial tilt.
Both Venus and Uranus rotate clockwise, as normally defined. However, the answer is "Venus", because that's the one that rotates slowly.

A planet rotates on its axis a point which travels through the north and the south of the planet. On earth the axis is found at the north and south pole of the earth.
The Earth rotates on its axis, which creates day and night as different parts of the planet face the sun.

A planet's axis is an imaginary line that runs through its center, connecting the North and South Poles. The tilt of this axis is responsible for the changing seasons on the planet as it orbits the sun.
An axis of rotation is the axis around which any body rotates, or the line joining the North Pole and the South Pole about which the planet Earth rotates on a daily basis.
The Earth rotates on its axis in one day. Strictly speaking that's the "sidereal day" not the "solar day". Also, by definition, each planet rotates once in a period that's the "sidereal day" for that particular planet.
