B Correct answer
Explanation

Ballast is the granular material (typically crushed stone) placed on the formation to provide a stable bed for sleepers. It distributes loads, prevents vegetation growth, and allows for drainage. Anchors are tie-down devices, subgrade is the prepared soil foundation, and chairs hold rails to sleepers.
