Multiple choice.
Solutions: obvious UR (67), or the old reliable xy-wing (367). The other (489) won't crack it.

Here is the grid after removing all basics that I noticed.
Earl's xy-wing does it.
I never noticed the UR, until mentioned by the other posters. Sure 'nuff.

| 49 14 149 | 26 3 5 | 267 67 8 |
