Jack was employed as a hard-rock miner for ABC Mines, Inc., which has 200 employees. One day, while Jack was doing his job, he was climbing a ladder provided by ABC that had been made by Ace Ladder. The ladder was defective (one of its rungs was not properly secured), although ABC did not know it. When Jack put his weight on that rung, it broke and Jack fell, injuring his back. Who can Jack sue in court for negligence? Explain why.

A. ABC only, for negligence in providing Jack the ladder and supervising his use of it B. Ace only, for negligence in making the ladder C. Both ABC and Ace D. Neither ABC nor AceJack can only recover workers' compensation
