Answer:
The correct answer is option A which is,"A disk formed of long trails of stars coiled into a spiral".
Explanation:
According to the shape of the milky way galaxies, it has a disk shape in the center of the galaxy and around this disk, there are two spiral-shaped arms coiled around each other.
It contains the stars, dust, and gases and its stars cannot be seen separately.
It is one of the spiral-shaped galaxies. Hence other options describing the elliptical shape are wrong.
Only option A is correct about milky way galaxy.
