Barb goes to Marlin's Department store to look for clothes. The store happens to be in the process of remodeling, and there is a lot of clutter in the aisle. Barb trips over the clutter and breaks her leg. Under the Second Restatement, what standard of care does the store have toward Barb under the circumstances?

a. None, because she came to the store voluntarily.

b. The store owes her a duty of only ordinary care because she is a trespasser.

c. Because she is a public invitee, the store must warn her of hazards that the store knows but that Barb is not likely to recognize.

d. Because Barb is a business visitor, the store must exercise reasonable care to protect her against dangerous conditions she is unlikely to discover.
