The status is Black lives.

White can not kill

Black wins the race.

White W3 is the strongest resistance White can offer. White can not atari Black due to shortage of liberties.

idigo's explanation

idigo: Black has a total of 5 liberties here, counting a twice since White must first play at b to remove the liberty at a. The marked white stones have effectively 3 liberties, since White will have to connect at b to win the race, giving White only 3 internal liberties (shared liberties in this semeai go to Black, who has the eye). Moreover, White can't get any more liberties with exchanges at c or d (c and d are miai for reducing White's liberties). Therefore I believe that White dies here.
