Which of the following bands is Tom DeLonge not a part of?

Tom DeLonge is not a part of the band +44. +44 was formed in 2005 by Blink-182 members Mark Hoppus and Travis Barker after Blink-182 went on an indefinite hiatus. Although DeLonge was originally intended to be a part of the new project, he eventually chose not to join and instead focused on his own musical endeavors. Thus, +44 consists of Mark Hoppus (vocals, bass) and Travis Barker (drums), with DeLonge absent from the lineup.
