Explanation Explanation/justification for the correct answer: Option (d) corticobulbar. Corticobulbar tract supplies innervations to the head and face. It is a direct pathway and project neurons to the brain stem. Hence, the option (d) is correct. Explanation for incorrect answer: Option (a) corticospinal. Corticospinal tract supplies to the neck, trunk, upper, and lower limb. It is a direct pathway and does not supply innervations to the head. Therefore, the option (a) is incorrect. Option (b) rubrospinal. The rubrospinal tract controls the fine motor movement of muscles in the upper limbs...
