A body cools from \[{{60}^{o}}C\] to \[{{50}^{o}}C\] in 10 minutes. If the room temperature is \[{{25}^{o}}C\] and assuming Newton's law of cooling to hold good, the temperature of the body at the end of the next 10 minutes will be [MP PMT/PET 1998; BHU 2000; Pb. PMT 2001]

• A.            \[{{38.5}^{o}}C\]                
• B.            \[{{40}^{o}}C\]
• C.            \[{{42.85}^{o}}C\]              
• D.            \[{{45}^{o}}C\]
