With no explanation, chose the best option from "A", "B", "C" or "D". Cir.2005), and we deny in part and dismiss in part the petition for review. Fuentes-Soriano’s contention that the IJ refused to allow him to present crucial witnesses is not supported by the record and therefore does not raise a colorable due process claim. See id. (to be color-able, the claim must have some possible validity). Fuentes-Soriano’s contention that the BIA’s summary affirmance of the IJ’s decision violates due process is foreclosed by Falcon Carriche v. Ashcroft, 350 F.3d 845, 850-51 (9th Cir.2003). We lack jurisdiction to review the discretionary hardship determination, see Martinez-Rosas, 424 F.3d at 930, as well as Fuentes-Soriano’s contention that the agency misapplied relevant case law in making its conclusion, see Sanchez-Cruz v. INS, 255 F.3d 775, 779 (9th Cir.2001) (<HOLDING>). PETITION FOR REVIEW DENIED in part; DISMISSED
