Default repeated usmle question 14

A 67 year old man visits his primary care physician for evaluation. Yesterday he had a seizure for the first time in his life. His co-workers told him that he lost consciousness all of sudden and started shaking his hands and legs for about two minutes. They called the ambulance but he was completely normal when paramedics arrived. He refused to go to the ER and told them that he will visit his regular doctor next day. His doctor orders some tests to exclude a brain tumor.
What is the most accurate test to confirm a diagnosis of brain tumor?
A- MRI of the brain
B- CT scan of the head
C- Hormonal assay
D- Brain biopsy

Default please read the question carefully

Some of the questions are tricky. ...The question asks to confirm not to diagnose. Confirming could be post-mortum or after surgery. Answer should be as accurate as the question.

Tissue-based pathological diagnosis is the criterion standard in the diagnosis of brain tumors. In situations in which surgical resection is not necessarily indicated but diagnosis of a brain lesion is needed to determine optimal treatment, a stereotactic brain biopsy offers a relatively safe and reliable method of obtaining diagnostic tissue.
