MACBETH. She should have died hereafter; There would have been a time for such a word. Tomorrow, and tomorrow, and tomorrow Creeps in this petty pace from day to day To the last syllable of recorded time; And all our yesterdays have lighted fools The way to dusty death. Out, out, brief candle! Life's but a walking shadow, a poor player That struts and frets his hour upon the stage And then is heard no more. It is a tale Told by an idiot, full of sound and fury, Signifying nothing.

 What does the phrase "creeps in this petty pace" refer to?

A)Death

C)Pace
D)Life
