Read the passage from a raisin in the sun.

bobo: man . . i didn't go to no springfield, yesterday.

walter (halted, life hanging in the moment): why not?

bobo (the long way, the hard way to tell): 'cause i didn't have no reasons to . .

walter: man, what are you talking about!

bobo: i'm talking about the fact that when i got to the train station yesterday morning—eight o'clock like we planned . . man—willy didn't never show up.

walter: why . . where was he . . where is he?

bobo: that's what i'm trying to tell you . . i don't know . . i waited six hours . . i called his house . . and i waited . . six hours . . i waited in that train station six hours . . (breaking into tears.) that was all the extra money i had in the world . . (looking up at walter with the tears running down his face.) man, willy is gone.

what tone does the playwright convey through bobo’s words "man, willy is gone"?

a. impatience and frustration because willy never arrives on time
b. sadness and regret because he is grieving willy, who recently died
c. shock and disbelief because willy has stolen his and walter's money
d. awe and surprise because he has no idea why willy left town
