Answer:

False

Explanation:

A main sequence star is a star that fuses hydrogen into helium.

A massive star needs a higher pressure and temperature at its core to keep itself from collapsing.

It must burn up its core supply of hydrogen more rapidly than a less massive star.

As a result, it spends less time in the main sequence before it becomes a red giant.
