Answer: (B)

Verified step by step guidance

1. Understand the role of interneurons: Interneurons are neurons that connect other neurons within the central nervous system. They play a crucial role in communication between sensory and motor pathways.
2. Evaluate statement I: Interneurons can be found in the spinal cord. This is true because interneurons are present in the spinal cord where they facilitate reflexes and other neural circuits.
3. Evaluate statement II: Interneurons only connect to motor neurons. This is false because interneurons can connect to both sensory and motor neurons, not just motor neurons.
4. Evaluate statement III: Interneurons can connect sensory and motor neurons. This is true as interneurons often serve as a link between sensory inputs and motor outputs, facilitating communication between these two types of neurons.
5. Determine the correct combination of true statements: Based on the evaluations, statements I and III are true, so the correct answer is 'I & III only.'
