Duffy Smith Started Having Nightmares and Chest Pains and Losing

Duffy Smith started having nightmares and chest pains and losing car keys and theater tickets.His wife urged him: "Take a vacation.See a physician.Do something!" So Duffy went to work on a Sunday afternoon.He threw out old files and glanced at the stack of weekly work logs accumulating next to the rubber tree plant.He sat down to eat the pizza he had ordered and looked at the work logs again.Then he retrieved the rest of them for a thorough study.Over the last quarter,the time spent on paperwork and reporting tasks had grown from 20 percent to 80 percent.He usually began to prepare the item status and inquiry report on Monday.Co-workers delivered rumors,management changed weekly priorities three or four times during the week,and balance estimates fluctuated constantly.So Duffy revised the report daily through the week until submitting it to management on Friday afternoon.The productive work of outside client contacts,which used to account for most of his time,was now squeezed into long lunches.Duffy decided to make some changes and left the building feeling better than he had in months.He told his wife,"If my new work plan works next quarter,we'll go to Calgary for a week in July." He started to prepare the item status and inquiry report on Thursday mornings,turning it in by noon on Friday.He scheduled contact meetings a week or two in advance,doing preparation work by phone and e-mail to increase client contact value.He followed up earlier and more thoroughly with each client.Duffy quickly returned to his old patterns of peaceful sleep and feeling good.Tomorrow Duffy and his wife go to Canada.Please answer the following question based on this scenario.
Duffy's stress symptoms were:

A) subtle.
B) familial.
C) eustresses.
