Correct option is C
The correct answer is (c) 29.5 days.
· The time period between a full moon and the next full moon is known as a synodic month, which is approximately 29.53 days long. This cycle is the basis for the lunar phases that we observe from Earth.
· The duration of 29.5 days reflects the moon's orbit around the Earth relative to the position of the Sun, effectively marking the cycle from one full moon to the next.
