The efferent fiber bundle of the substantia nigra transmits dopamine to one of the following areas: (A) Thalamus, (B) Corpus striatum, (C) Tegmentum of pons, (D) Tectum of midbrain
Answer is B. Connections in Basal ganglia

Substantia nigra pars compacta (SNPC) to Striatum (Caudate nucleus & Putamen)- Dopaminergic 
Striatum to Substantia nigra pars reticulata (SNPR)- GABA 
Striatum to Globus pallidus inner segment & external segment- GABA 
Globus pallidus external segment to subthalamic nucleus and internal segment- GABA​
Subthalamic nucleus to Globus pallidus external segment and internal segment.- Glutamate​
Within the striatum- Cholinergic interneurons.
