Final answer:
The Milky Way Galaxy contains approximately a few hundred billion stars, which shows the enormity of our Galaxy that spans about 100,000 light-years across.
Step-by-step explanation:
The number of stars in the Milky Way Galaxy is approximately a few hundred billion (Answer C). Our Galaxy is a vast expanse of space, containing hundreds of billions of stars, surrounded by massive amounts of gas and dust. Although we can see approximately 9,000 stars with the unaided eye from Earth, this number is only a tiny fraction of the total. The full extent of the Milky Way is estimated to be about 100,000 light-years in diameter, and within this space, there are roughly 100 billion stars, indicating the staggering scale of our Galaxy.
