Answer: it is the third but there is a typo. It is C. 267 - 150 = 117

Explanation:

You can do that estimation searching to make a quick verification, because adding rounding 154 to the tens leads to 150 and it is very easy to subtract 267 - 150 instead of 267 - 154, driving to a quick approximate check of the subtraction.
