From the option given the correct option is option b
B. A direct extension of the infectious molar
C. Waiting too long in the ED to be seen
D. From a distant site of undiscovered infection
The option A is not a correct option as a Motor Vehicle Accident with no serious injuries is not a likelihood of the brain abscess as confirmed by the MRI.
The option B can be correct as the infectious molar can cause the abscess to develop in the brain.
The option C is not correct as there is an underlying cause which has caused this abscess. Waiting in the ED can only aggravate the situation which is not a case here.
The option D which indicate the distant site of an undiscovered infection can be an option.
So the two possible answers are Option B and D.
Now the likelihood of the undiscovered distant infection is less as if the infection is not discovered yet, it is very rare that it would affect the brain first so the correct option remaining by the process of elimination is option B.
