Solution:'Estragon' and 'Pozzo' are the characters that are figured in Samuel Beckett's 'Waiting for Godot'. Estragon is one of the tulo men (Often referred to as 'tramps') who are waiting for Mr. Godot. He is the first to appear in the play and is more docile and timid than his friend Vladimir.
'Pozzo' is the bold, brutal, insensitive, and overbearing figure who intimidates Estragon and Vladimir in the first act of play after he drives his slave, Lucky, in the scene. Hence, option (a) is correct.
