b
Inability to understand or produce speech, left arm paralysis

c
Left arm and leg paralysis
QuestionChoice
A left MCA lesion would also produce contralateral visual-field defects - therefore we would expect right-sided visual-field defects. However, we would expect right-sided motor dysfunction instead of left-sided dysfunction as the left middle cerebral artery supplies blood to the left primary motor cortex, which controls motor function on the right side of the body.

e
Right visual-field defect, left arm and leg paralysis
QuestionChoice
A left MCA lesion would also produce contralateral visual-field defects - therefore we would expect right-sided visual-field defects instead of left-sided ones.

d
Left visual-field defects, inability to understand speech
QuestionChoice
The left middle cerebral artery (MCA) supplies Broca's area (production of speech) and Wernicke's area (understanding of speech).

It also supplies blood to the left primary motor cortex, which controls motor function on the right side of the body.

A lesion in these areas would therefore produce impairments in producing and understanding speech, and contralateral paralysis.
