(B) Observe the sequence by pairing the numbers from the ends towards the center.Pairing the numbers: $(13, ?), (21, 12), (29, 92), (34, 43)$.In each pair,the digits of the numbers are reversed.For the pair $(21, 12)$,$21$ reversed is $12$.For the pair $(29, 92)$,$29$ reversed is $92$.For the pair $(34, 43)$,$34$ reversed is $43$.Following this pattern,for the pair $(13, ?)$,the number $13$ reversed is $31$.Therefore,the missing number is $31$.

$13, 21, 29, 34, 43, 92, 12, ?$
