Answer:
The line in the excerpt from Eugene O'Neill's "Beyond the Horizon" that reflects the idea of pursuing one's dreams is:
And I’d promise myself that when I grew up and was strong, I’d follow that road, and it and I would find the sea together. (With a smile) You see, my making this trip is only keeping that promise of long ago.
Explanation:
The question is not complete since it does not provide the exact options, here are the options:
A) ROBERT: You'll have to, to understand. Well, in those days, when Ma was fixing meals, she used to get me out of the way by pushing my chair to the west window and telling me to look out and be quiet. That wasn't hard. I guess I was always quiet. RUTH: (compassionately) Yes, you always were—and you suffering so much, too!
B) ROBERT: (musingly) So I used to stare out over the fields to the hills, out there—(He points to the horizon) and somehow after a time I’d forget any pain I was in, and start dreaming. I knew the sea was over beyond those hills,—the folks had told me—and I used to wonder what the sea was like, and try to form a picture of it in my mind.
C) (With a smile) There was all the mystery in the world to me then about that—far-off sea—and there still is! It called to me then just as it does now. (After a slight pause) And other times my eyes would follow this road, winding off into the distance, toward the hills, as if it, too, was searching for the sea.
D) And I’d promise myself that when I grew up and was strong, I’d follow that road, and it and I would find the sea together. (With a smile) You see, my making this trip is only keeping that promise of long ago.
The given options talk about how the character daydreams about the possibilities of other places and the discovery of fantastique views as well as living new adventures but the one that talks about going forward on that is option D since it makes the promise of actually making all those dreams come true.
