Since it is given that ab is divisible by \(13\) we should first check ans choices to eliminate options that are not divisible by \(13\):

option a: \(10\) is below \(13\)so it is not divisible by \(13\)

option b: \(25\) is one less than \(26\) so it is also not divisible by \(13\)

option c: \(52\) is divisible by \(13\) so let us see if the total number replaced by \(52\) for the position ab is divisible by \(25\)

\(\frac{2525}{25}= 101\)

option C
