Answer "D" and "E" would at least imply that there was no issue with the crack, and it only needs repair ... which may not be the case.
The wall type is not noted or really the issue, but it can be inferred that it's concrete since there is no step in the crack noted. Also there is no mention of age, so it can be taken it's other than a new wall. Although, IMHO it's the age of the crack ... and not the home ... that is important.
New homes sometimes move a little and then stabilize, and older homes sometimes have a change in situation that causes cracks (seasonal rainfall, groundwater, grading, roof drainage, etc). But in performing an evaluation as an engineer I would be more suspicious about cracking in a new home, as opposed to cracking in an older home.
For those that answered "A" I would give partial credit since settlement is suspected and recommending an SE gets the monkey off your back ... ![icon_wink.gif](upload://ssT9V5t45yjlgXqiFRXL04eXtqw.gif)
BTW ... a penny is almost exactly 1/16" ... so an 1/8" crack would be about the width of two Penny's ...

I am absolutely amazed sometimes by how much thought goes into doing things wrong
