With no explanation, chose the best option from "A", "B", "C" or "D". as required by Faretta v. California, 422 U.S. 806, 835, 95 S.Ct. 2525, 45 L.Ed.2d 562 (1975). The district court agreed that the lack of such warnings violated the Sixth Amendment but concluded that the error was harmless. Dallio v. Spitzer, 170 F.Supp.2d at 336-38. We affirm the district court’s judgment without reaching the question of harmless error. See Boule v. Hutton, 328 F.3d 84, 92 (2d Cir.2003) (noting our ability to affirm a judgment on any ground appearing in the record, whether or not relied on by the district court). Although explicit warnings as to the dangers and disadvantages of self-representation are certainly advisable to ensure knowing and intelligent waivers of the right to counsel, see Johnson v. Zerbst, 304 U.S. 458, 468, 58 S.Ct. 1019, 82 L.Ed. 1461 (1938) (<HOLDING>), we conclude that it is not clearly

A: holding that accused must competently and intelligently waive the right to counsel
B: holding that one must voluntarily and intelligently waive the right to counsel
C: recognizing the right to waive a jury trial
D: recognizing that the sixth amendment guarantees a defendant the right to counsel and the right to waive counsel
A.
