C.(1 - √2 + (√2 - √3 + (√3 - √4 + ..... + (√15 - √16) Since all the other numbers will be cut off from each other so - =1-√16 =1-4 = -3 So the correct answer is option C.
C.(1 - √2 + (√2 - √3 + (√3 - √4 + ..... + (√15 - √16) चूँकि बाकी सभी संख्या एक दूसरे से कट जाएँगी इसलिए - =1-√16 =1-4 = -3 इसलिए सही उत्तर विकल्प C है।
