Answer:
Chorus.
Explanation:
William Shakespeare's "Romeo and Juliet" revolves around the tragic love story of two young lovers. The story deals with themes of love, family, loyalty, patriarchy, death, etc.
The given lines<em> "from forth fatal loins of these two foes, A pair of star-crossed lovers take their life" </em>are taken from the Prologue of the story. Said by the Chorus as a prologue, the lines talk of how the <em>"two foes"</em>- the Montagues and the Capulets will produce two <em>"star-crossed lovers"</em>. And because of that enmity between their families, they will take their life.
Thus, the correct answer is the Chorus.
