D. Out out brief candle

 And all our yesterdays have lighted fools

The way to dusty death. Out, out, brief candle!

Shakespeare

Those lines come from Macbeth by William Shakespeare—specifically from Macbeth’s famous soliloquy in Act 5, Scene 5.

In this moment, Macbeth has just learned of Lady Macbeth’s death, and he reflects on the futility and brevity of life.

• “All our yesterdays have lighted fools / The way to dusty death”
  He’s saying that everything in the past (“yesterdays”) merely leads people toward death. Life’s experiences don’t add up to lasting meaning—they just guide us to our end.
• “Out, out, brief candle!”
  Life is compared to a candle flame—fragile, short-lived, easily extinguished. The repetition (“out, out”) expresses frustration and emptiness, almost like he’s dismissing life itself.

Overall, it’s one of Shakespeare’s bleakest reflections: life is temporary, repetitive, and ultimately insignificant in the face of death.

If you want, I can  break down the rest of the “Tomorrow, and tomorrow, and tomorrow…” speech—it continues this same haunting idea.
