To determine if a number is divisible by 11, we can use the divisibility rule for 11.
The divisibility rule for 11 states that a number is divisible by 11 if the difference between the sum of its digits at odd positions and the sum of its digits at even positions is either 0 or a multiple of 11.
Let's apply this rule to the number 143143143143:
Sum of digits at odd positions: 1 + 3 + 4 + 1 + 4 + 3 = 16
Sum of digits at even positions: 4 + 1 + 3 + 4 + 3 + 1 = 16
The difference between the sum of digits at odd positions and the sum of digits at even positions is 16 - 16 = 0.
Since the difference is 0, the number 143143143143 is divisible by 11.
Therefore, the correct answer is A) True.
