Alert police officers noticed that a late-model "Belchfire 500" automobile was being driven at an excessive rate of speed. The car, driven by Doofus, was pulled over to the curb. As Officer Smith issued a speeding citation to Doofus, her partner, Jones, fed the license plate numbers into the police computer. It turned out that the Belchfire had been very recently reported as stolen. Doofus was unable to produce satisfactory registration papers and was arrested for car theft. At the police station, Smith gave Doofus the standard Miranda warnings, and Doofus agreed to answer Smith's questions regarding a local "chop-shop" network, which arranged for the theft of expensive automobiles so that they could be cut up for parts. After a while, Jones suggested, "Let's break for lunch." He and Smith escorted Doofus to a nearby cafeteria. During the course of their lunch, which lasted about an hour, Smith noticed that Doofus, who was otherwise rather shabbily dressed, was wearing an obviously expensive "Xelor" watch. Upon their return to the station, and without giving any new Miranda warnings, Smith resumed interrogation of Doofus. She asked Doofus about a recent home invasion in the swank "Notting Hill" neighborhood, where a quantity of valuable jewelry, including a "Xelor" watch, was taken. Doofus thereupon confessed to the home invasion, and was indicted on the home invasion charge, a felony under the jurisdiction's modern criminal code. If Doofus files an appropriate motion to prevent the confession from being admitted at his trial, Doofus will probably:
A. Succeed, because the police did not repeat the Miranda warnings before questioning Doofus about another crime.
B. Succeed, because the police acted in a custodial setting.
C. Fail, because Doofus was not in custody on a home invasion charge.
D. Fail, because the original Miranda warnings given Doofus were sufficient under the circumstances. 
Choose A, B, C or D as your solution.
