"A Customer Slips and Falls on a Wet Floor of a Store

"A customer slips and falls on a wet floor of a store." The correct responsibility of the owner is?

A) The property owner must maintain their property so no one is injured. If any injury occurs the property owner is always liable.
B) The property owner is liable only if the customer has made a purchase and the floor was wet more than one hour after an inspection occurred or was due to occur.
C) The property owner has no duty to maintain their property in a safe manner unless the property owner knows that an injury has occurred in the past.
D) The property owner must maintain their property in a reasonably safe manner so that a visitor will not be injured on the property while the property is open to the public or at a time when it is foreseeable that a member of the public would be on the property.
