Answer:

B

Step-by-step explanation:

note there is a difference of 2 between consecutive odd integers.

let the 2 integers be n and n + 2, then

n + n + 2 = 56, that is

2n + 2 = 56 ( subtract 2 from both sides )

2n = 54 ( divide both sides by 2 )

n = 27

Thus the smaller integer is 27 → B

The larger integer is n + 2 = 27 + 2 = 29
