Hydroxy ethanoic acid is a white solid, ...

Hydroxy ethanoic acid is a white solid, readly soluble in water. It is prepared by the hydrolysis of chloroethanoic acid with sodium hydroxide followed by acidification. It exhibits the properties of both a monocarboxylic acid and a primary alchol. In addition, it undergoes reactions which neither a carboxylic acid nor a primary alcohol can undergo.
Which of the following products is formed when hydroxyethanoic acid is being heated?

A

`HO-CH_3`

B

C

`H-overset(O)overset(||)C-overset(O)overset(||)C-H`

D

`HO-overset(O)overset(||)C-overset(O)overset(||)C-H`
