A
Corpus callosum and basal ganglia
B
Corpus striatum
C
Caudate nucleus and globus pallidus
D
Lateral surface of the cortex
Explanation: 

Detailed explanation-1: -To summarize, the ACA supplies the medial and superior parts of the frontal lobe, and the anterior parietal lobe.

Detailed explanation-2: -The blood supply to the basal ganglia comes primarily from the middle cerebral artery (#4796), in particular, the lenticulostriate branches, seen on a postmortem frontal angiogram in #9811, and as small holes in a gross horizontal specimen in #5631.

Detailed explanation-3: -Blood supply of the corpus callosum is assured by two arterial systems, the carotid system mainly and the vertebrobasilar system accessorily. The carotid system intervenes via the pericallosal artery, portion of the anterior cerebral artery distal to the anterior communicating artery.
