The sharp transition seen in Figure suggests that

A. Proteins can be denatured by any treatment that disrupts the weak bonds stabilizing tertiary structure, such as heating, or by chemical denaturants such as urea or guanidinium chloride.

B. A comparison of the degree of unfolding as the concentration of denaturant increases reveals a sharp transition from the folded, or native, form to the unfolded, or denatured form, suggesting that only these two conformational states are present to any significant extent.

C. A similar sharp transition is observed if denaturants are removed from unfolded proteins, allowing the proteins to fold.

D. Protein folding and unfolding is an “all or none” process that results from a cooperative transition .

Two families travelling from Meerut to Nagpur (which is 390 km distance) in two cars, started at the same time travelling through the same road, without any traffic block or any abjections. The ratio of the speed of the car-1 and car-2 is 6:7. After how long travelling car-1 has to exchange the speed with car-2 so that they could each the destination at the same time?
