Answer 1

The correct answer is C. Halogeno-alkanes can be prepared from a HX (halogen) and alcohol through a substitution reaction. This reaction is commonly known as the halogenation of alcohols. In this reaction, the halogen atom replaces the hydrogen atom in the alcohol molecule, resulting in the formation of a halogeno-alkane.
