Liability of Occupier for Acts of Third Person

Aapke paas ek shop hai aur wahan aai ek third party ne ek customer ko peele ki goli maar di hai. Aap shopkeeper ki tarah aapka kya responsibility hoga?

A) Aapko koi bhi deneh ki zaroorat nahin hain. B) Aapko customer ko deneh ki zaroorat hai. C) Aapko third party ko deneh ki zaroorat hai. D) Aapko koi deneh nahin hain, lekin aapka property ke liye khara haath hai.

Mujhe lagta tha ki option A sahi hai, lekin mujhe pata lag gaya hai ki woh galat hai.

Please share aapka anumaan aur kya aapka explanation hoga?
