Answer

Answer:

X: A white - dwarf is part of the cycle. Y: Nuclear fusion forms hydrogen in the main sequence star. Z: A supernova is part of the cycle.

Explanation:

Step1: Analyze low - mass stars

Low - mass stars end as white dwarfs. So, X should have a characteristic of low - mass stars like "A white dwarf is part of the cycle".

Step2: Analyze commonality

Both low - mass and high - mass stars undergo nuclear fusion to form hydrogen in the main sequence phase. So, Y is "Nuclear fusion forms hydrogen in the main sequence star".

Step3: Analyze high - mass stars

High - mass stars end in a supernova explosion. So, Z is "A supernova is part of the cycle".
