Explain the Mechanism of Action of Emollients That Are Used

Explain the mechanism of action of emollients that are used as laxatives.

A) They work by releasing carbon dioxide gas that pushes against the rectum wall and induces muscle contraction and stool movement.
B) They soak up water and soften the stool, which results in a swelling action that distends the rectum and initiates defecation.
C) They consist of a mixture of sodium and magnesium salts that attract water, which results in the formation of a more liquid stool.
D) They penetrate the fecal mass and ease the passage of the stool through the rectum due to their oily nature.
