Answer:
FALSE
Step-by-step explanation:
The rotation of a planet is determined by the rotation of the initial mass that formed the planet.
The retrograde spin has nothing to do with the length of the solar day.
One reason why the rotation of Venus is slow may be due to the tidal lock and the sun's gravity. One solar day in Venus lasts 243 Earth days and it orbits the sun every 224.7 Earth days.
