White vinegar is an alternative cleaning product that :

soften water

cut grease

remove stains from carpets

attack rust

Option B, cut grease

Explanation:

Vinegar is acetic acid and thus it can be used as a degreaser. It can be used for cleaning non-absorbing surfaces because absorbing surfaces shall soak the vinegar . When vinegar is applied on any surface containing grease, it cut through it without leaving any residue as it contains natural acids. Acetic acid can also be used along with water as it makes the acetic acid a little mild thereby making it safer for handling.
