Question 14

In astronomy (a subfield of Natural Science, specifically Physics or Astronomy which can be under "Others" in Natural Science subfields here), the term "waxing" in relation to the moon means the illuminated part we see is growing. So the correct option is the one stating the illuminated portion appears to be increasing.

In astronomy, "waning" for the moon means the illuminated portion we observe is getting smaller (decreasing). This is a key concept in lunar phases.

Answer:

A. The illuminated portion of the moon appears to be increasing.
