Question

A. expand
B. emit X-rays
C. run out of fuel
D. begin rotating faster

Answer 1

C, when a star dies it collapses in on itself and destroys everything in a supernova

Answer 2

The correct answer is option C. "run out of fuel".

Step-by-step explanation:

Hydrogen is the fuel of the stars, stars use it to produce nuclear reactions that help them to fight against their own gravity forces. After million of years stars run out of it, which make them collapse into their own weight. When massive stars go trough this process, usually they explode into supernovas and black holes are created.
