For a star with a mass of 6 times that of the Sun, the brightest stage in its life cycle is typically during the **red giant** phase.
In general, massive stars go through a series of stages in their lifecycle. They are typically more luminous during their red giant phase after exhausting the hydrogen in their cores and beginning to fuse helium and other heavier elements.
While on the main sequence, the star is still very luminous, the red giant phase sees a significant increase in brightness due to the expansion of the outer layers and increased energy output.
So the correct answer is **red giant**.
