Every positive whole number n such that n+%3E+1 can be written in the form a%2Bb where 'a' and 'b' are positive whole numbers (it is possible that a = b)

n = 1 is not able to be written into the form a%2Bb because either 'a' or 'b' would have to be 0. But this contradicts their condition that a+%3E+0 and b+%3E+0

So the final answer is B. 1 since there is only one number (the number 1 itself) that cannot be written as the sum of two positive integers.
