A) \[5\Rightarrow 7\Leftarrow 2\Downarrow 3\Uparrow 5\text{ }\otimes 10\]
B) \[2\Downarrow 5\Leftarrow 6\Rightarrow 2\otimes 6\]
C) \[2\Downarrow 6\Uparrow 4\Leftarrow 3\Rightarrow 7\otimes 0\]
D) \[5\Rightarrow 7\Leftarrow 3\Uparrow 2\otimes 4\]
Correct Answer: B
Solution :
: \[2\Downarrow 5\Leftarrow 6\Rightarrow 2\otimes 6=2\times 5-6+2\]= 6 i.e., 6=6 which is true.You need to login to perform this action.
