Agree MCA distribution.
MCA would not however affect lower limbs (that would be ACA),
so i think its B. (Aphasia because of temporal lobe involvement).

Yeah, agree with you, B
I am very terrified with neuroscience. I read many times but then forgot.
Middle Cerebral Artery:
Spastic paresis of contralateral lower face and upper limb
Anesthesia of contralateral face and upper limb
Aphasia
Contralateral superior quadrantanopsia
other: left-sided neglect (if dominant afftected)

Thanks for all your help Robin.
Don't be terrified... Just remember the homonculus and try to picture it....

Lower Limb is ACA. (Medial)
Everything else is MCA. (Lateral)

Dysarthria is an acquired neurological disorder of speech caused by damage to cranial nerves or the frontal lobe (motor cortex). Dysarthria is completely a motor problem. Symptoms may include slurred speech, paralysis of the speech musculator, or swallowing problems. One side of the body is usually paralized.

Hemianaopia should require occipital lobe involvement and numbness shoudl require parietal or thalamic involvement.
The answer is B and the aphasia is likely to be only Broca's.

B. exclude choices with defects in u and lower limbs together in this case coz of different vascular supply. B goes with what is shown in Dr virgo's homonculus
