For a number $$657423547X46$$ to be divisible by 11, the difference between the sum of numbers at even position and odd position should be either '0' or '11'.
Sum of digits at odd position (starting from right) = $$6+X+4+3+4+5=(22+X)$$
Even positions = $$4+7+5+2+7+6=31$$
=> $$22+X-31=0$$
=> $$X=9$$
=> Ans - (B)
