Answer:
d. It is easy and inexpensive to form.
Explanation:
Sole proprietorship is a company formed by an individual it is run by that individual. It generally do not require much of funds, although since there is only one reporting person thus, he is liable for every profit or the loss.
There stands an unlimited liability on such person and he can not withdraw from such liability.

Accordingly, option d is correct.
