Confusion in Leasehold Estate: Can Someone Explain?

Maine ye question 3 baar padha aur abhi bhi samajh nahi aaya 😭. Iska problem ye hai ki kya leasehold estate ka khyaal karna jaruri hai jab ek property ka owner lease period mein hua jaata hai, lekin uska apna ownership banta rehta hai? Jaise ke example mein, apne dad se property milkar aaya hai jise unhone 30 year ka lease liya tha, aur ab main us property ka owner hua hai. Ab kya maine use transfer karna hoga? Aur kya yeh leasehold ka ek form hai? Maine padha hai ki jo property leasehold mein aata hai, use freehold mein transfer karna mushkil karta hai, lekin kya ye koi rule hai ya shart hai?
