What's the most logical way to complete this passage?

The White House refused on Thursday to publicly incriminate North Korea in a cyber hack on computers at Sony Pictures, even though senior U.S. officials have already indicated in private that the country was 'centrally involved.' The president's spokesman instead claimed that the 'destructive activity with malicious intent' was carried out 'by a sophisticated actor.' 'I am not in a position to confirm any attribution at this point,' White House Press Secretary Josh Earnest said. He promised that the Obama administration was taking the matter 'seriously,' however, and that investigators are 'mindful of the fact that we need a proportional response.' He also revealed that retaliatory actions may be kept secret.

Vilket är det mest logiska sättet att slutföra detta avsnitt? Vita huset vägrade på torsdag att offentligt anklaga Nordkorea i en cyberhack på datorer på Sony Pictures, även om höga amerikanska tjänstemän redan har antytt privat att landet var "centralt involverat". Presidentens talesman hävdade istället att den "förstörande verksamheten med illvillig avsikt" utfördes "av en sofistikerad skådespelare". "Jag är inte i stånd att bekräfta någon attribuering vid denna punkt," Vita husets pressekreterare Josh Earnest sade. Han lovade dock att Obamaadministrationen tog frågan ”allvarligt”, och att utredarna är ”medvetna om att vi behöver ett proportionellt svar”. Han avslöjade också att vedergällningsaktioner kan hållas hemliga. ALTERNATIV: - Josh Earnest har sagt att det inte är ansvarigt för cyberattacken, trots lovande " skoningslösa motåtgärder" i sommar om USA:s regering tillät att filmen släpptes. - Nordkorea har sagt att det inte är ansvarigt för cyberattacken, trots lovande " skoningslösa motåtgärder" i sommar om USA:s regering tillät att filmen släpptes. - Obama har sagt att det inte är ansvarigt för cyberattacken, trots lovande " skoningslösa motåtgärder" i sommar om USA:s regering tillät att filmen släpptes. - Sony Pictures har sagt att det inte är ansvarigt för cyberattacken, trots lovande " skoningslösa motåtgärder" i sommar om USA:s regering tillät att filmen släpptes. - USA har sagt att det inte är ansvarigt för cyberattacken, trots lovande " skoningslösa motåtgärder" i sommar om USA:s regering tillät att filmen släpptes. - Vita huset har sagt att det inte är ansvarigt för cyberattacken, trots lovande " skoningslösa motåtgärder" i sommar om USA:s regering tillät att filmen släpptes.
