Reference - Overextended Debtor. Dennis purchased a big screen television from ABC Electronics and financed the purchase through ABC Electronics based on an agreement granting ABC Electronics a security interest in the television and requiring that Dennis make monthly payments. Three months later, because Dennis had bought a boat, a new car, an expensive engagement ring for his girlfriend, and some other items, he was unable to continue making payments on the television. The manager from ABC Electronics called and asked Dennis to return the television. Dennis refused on the basis that ABC Electronics never perfected its interest in the television. Which of the following is correct regarding the statement of Dennis that the security interest was not perfected?

A) Dennis is wrong because the security interest perfected automatically.
B) Dennis is wrong because the security interest perfected when he was still in possession of the collateral 30 days after the purchase.
C) Dennis is wrong because the security interest perfected when he was still in possession of the collateral 60 days after the purchase.
D) Dennis is correct because in the case of luxury goods, a financing statement must be filed within 10 days.
E) Dennis is correct because regardless of whether or not a luxury good was involved, the interest was never perfected.
