TPA ka maze - Lease and sublease - kya hai difference?

yaar samajh nahi aaya, kya karein? Maine TPA ka syllabus padha, aur phir se confusion ho gayi. Yeh question padhta hai "Lease and Sublease - difference and significance". Samajh mein aaya hai ki Lease mein property ki ownership ke liye koi vachan hota hai, phir sublease mein koi aur shamil hota hai, yeh ownership ka vachan dete hain. Lekin kya yeh ek hi chit ki baat hai, ya dono alag-alag chizein hain. Maine suna hai ki sublease kuchh chote-chote portions mein hota hai, while lease badi portion ka hai.
