In about 12 hours

Answer 1

Answer:

In about 30 days

Explanation:

Assume Xavier sights a full moon today, it'll take around 29.5 days to see the moon at that size again.

Analysing each of the given options, only option D answers the question because 29.5 days can be rightly said to be about 30 days.
