Answer
Among the given options, all can be produced through reduction of aldehydes or ketones. However, considering the structure and the positions of carbon atoms, 2,2-dimethylpropan-1-ol cannot be synthesized through the reduction of a typical aldehyde or ketone due to sterics preventing the reaction. Hence, the correct answer is A) 2,2-dimethylpropan-1-ol.
