The Correct Option is B

Solution and Explanation


Step 1:
Check divisibility by 11. \[ 154=11\times14 \] \[ 286=11\times26 \] \[ 341=11\times31 \] \[ 495=11\times45 \] \[ 572=11\times52 \] \[ 781=11\times71 \]

Step 2:
Check 683. \[ 683\div11=62.09\ldots \] Hence 683 is not divisible by 11. \[ \boxed{683} \]
