Answer

Brief Explanations:

The dorsal column is mainly responsible for transmitting sensory information related to fine touch, pressure, vibration, and proprioception. An injury to it would likely lead to a loss of sensation in these modalities. Options B (loss of control over all involuntary movements) is more related to other neural structures like the autonomic nervous system. Option C (inability of the body to maintain homeostasis) is a broader function involving multiple systems. Option D (inability to regulate the sleep - wake cycle) is related to structures like the hypothalamus. Option E (loss of motor control) is related to motor pathways like the corticospinal tract.

Answer:

A. loss of sensation to pressure and touch
