Answer: C - Darlene owes a duty of care to others. The major premise establishes a duty of care that is owed by all drivers to others, and the minor premise establishes that Darlene is within the class of drivers. Since Darlene is within the class of drivers, she also owes a duty of care to others. Answer A is not correct because the duty is owed to others, not to automobiles. Answer B is not correct because it simply restates the minor premise. Answer D is not correct because it is too broad (uses the term "all"), and because it does not draw a conclusion from the minor premise.
