The status is Black lives.
White 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.
