Sally quit her job because her supervisor Ace Ventura chewed sunflower seeds all day. The popping noises were driving her crazy. Sally will prevail in a constructive discharge claim only if:

a) her employer failed to take action to stop the supervisor's actions.

b) her coworkers defend her decision to quit.

c) a previous employee quit for the same reason.

d) a reasonable person would consider chewing sunflower seeds tantamount to an intolerable work environment.
