Solution

The correct option is C Baking soda
Onion acts as an olfactory indicator. When it comes in contact with an acid, it retains its smell but in the presence of a base, it loses its characteristic smell and becomes odourless. Baking soda is basic, vinegar and lemon juice are acidic and distilled water is neutral. So, to remove the smell of onion from the piece of cloth, Alex must use baking soda.
