Todd said to his wife, "Honey, you know how we have always wanted to be in business for ourselves? Well, today I did it! I have rented a 3,000 square foot business, hired six employees, ordered office furniture; we are in business." During the first three weeks, Todd was surprisingly successful, but one morning he was so down he could not get out of bed. He stared at the ceiling day after day while his wife attempted to rescue their investment. Todd appears to be suffering from:

a. depression.

b. bipolar disorder.

c. illusion of grandeur.

d. a conversion disorder.

I think it is b.

I agree.

Definitely B.

To determine Todd's condition, let's analyze the given information.

Todd's initial statement indicates that he was ambitious and motivated to start a business. He took several practical steps such as renting a space, hiring employees, and ordering office furniture. Additionally, he experienced initial success during the first three weeks.

However, Todd's sudden change in behavior, where he is unable to get out of bed and shows no interest in his business, suggests a significant decline in mood and motivation. This can be indicative of depression, as described in option a.

Bipolar disorder, option b, is characterized by extreme shifts in mood ranging from depressive episodes to manic episodes. Since the information doesn't provide evidence of Todd experiencing manic episodes, it is less likely to be bipolar disorder.

Option c, illusion of grandeur, refers to individuals having an exaggerated sense of importance or power. Although Todd showed ambition in starting the business, there is no indication that he believed himself to be more important or powerful than he actually was. Therefore, this option can be ruled out.

Lastly, option d, a conversion disorder, involves the presence of physical symptoms without any underlying medical explanation. The given information only describes Todd's psychological symptoms, and there are no mentions of physical symptoms, making this option less likely.

Based on the provided information, depression, option a, appears to be the most suitable answer.
