Stars appear to rise and set due to Earth's rotation, which happens from west to east. This makes all observable stars seem to rise in the east and set in the west, making it unlikely to find a star that behaves otherwise. Therefore, the correct option is option c.
The best explanation for the scenario where a star rises in the west and sets in the east is option c) This statement does not make sense. The stars appear to rise and set because of Earth's rotation. This perceived motion of the stars is due to our planet's daily rotation on its axis, not the stars themselves moving.
This rotation happens from the west towards the east, which causes stars to appear to rise from the east and set in the west. This pattern remains consistent for all observable stars from Earth. Therefore, it's not feasible to find a star that behaves contrary to this mechanism under general conditions.
Note: The question is incomplete. The complete question probably is: "Although all the known stars rise in the east and set in the west, we might someday discover a star that will rise in the west and set in the east." Choose the correct explanation why does the statement above make sense (or is clearly true) or does not make sense (or is clearly false).
a) This statement does not make sense. The stars moves because of the Galaxy's rotation around it center. So, during the day, al the stars must move in the same direction.
b) This statement makes sense. The North Star itself does not appear to move usually, but sometimes the precession occurs. Precession changes the tilt of Earth's axis and could make the North star set in east or rise in west.
c) This statement does not make sense. The stars appear to rise and set because of Earth's rotation. So, during the day, all the stars must move in the same direction.
d) This statement makes sense. The star appear to rise and set because of the sum of Earth's rotation and changing the seasons. So, in the night of solstice, the North Star could move in the opposite direction to other stars.
