Delbert takes out a $10,000 loan from First National Bank (FNB) and grants FNB a security interest in his Ford Explorer.  FNB timely files a UCC-1 financing statement covering the vehicle. Some months later, Delbert transferred the Explorer to Travis in satisfaction of a personal debt owed by Delbert to Travis. Subsequently, Delbert defaulted on his loan and FNB sought to repossess the vehicle.

Which of the following statements is most accurate?

A) Because FNB filed the UCC-1 financing statement, Travis was "on notice" of FNB's security interest and thus FNB can successfully repossess the vehicle from Travis.

B) The filing of the UCC-1 financing statement alone was inadequate to defeat the claim of a third party like Travis who acquired the vehicle without knowledge of a security interest on the vehicle.

C) The filing of the UCC-1 financing statement was adequate to perfect the security interest in the Explorer and thus for the security interest to remain effective against a third party who acquired the vehicle without knowledge of the security interest.

D) Even if Travis had actual knowledge of the security interest on the vehicle when he bought it from Delbert, FNB will only be successful in repossessing the vehicle from Travis if FNB had perfected the security interest in accordance with the state's certificate of title statute.
