Answer: (A)

Ma Zi Ren Wan treats constipation by both moistening the intestines and promoting bowel movement, balancing lubrication with a controlled purge. The core idea is to use a strong intestinal lubricant along with herbs that move qi and help stool pass smoothly, all while harmonizing the formula so it isn’t too harsh.

Huo Ma Ren provides the main moistening effect, deeply lubricating the intestines to ease dryness. Xing Ren adds moisture and helps guide qi downward, supporting natural bowel movement. Zhi Shi and Da Huang work together to move stagnated qi and facilitate the passage of stool. Hou Po helps promote movement and resolve dampness, preventing dullness or fullness from slowing things down. Bai Shao contributes yin-nourishing and harmonizing properties, softening harsh effects and protecting the stomach during the purgative action.

This combination covers lubrication, qi movement, and balanced support, which is why it fits Ma Zi Ren Wan best. Missing any of these roles would weaken the formula—without the moisture, stools remain dry; without qi-moving components, stagnation blocks passage; without harmonizing support, the purgative action can be too harsh.
