B Correct answer
Explanation

Among these numbers, 45 is the only one without a special mathematical property. 11 and 88 are palindromes (read the same forwards and backwards). 69 is strobogrammatic (appears the same when rotated 180 degrees). 45 has neither property, making it the true odd one out.
