The drawing is a little unclear I think.

If you read the actual answer, you'll notice that there are two options for the final grouping:

A'BD
 or
BCD

BCD is the grouping in red in your answer, while A'BD is the grouping:

A'BD grouping

So there are two options for grouping that lone 1, and the answer considers both of them. It just doesn't draw both of them.

The giveaway is that a single cell needs 4 terms to specify it -- that 1 on its own would be A'BCD. However there aren't any elements with 4 terms in the answer, which means that the answer must have grouped it with another cell.
