Step 1: Understanding the Concept:
Aflatoxin binders are used in animal feed.
They have different binding affinities.
Step 2: Key Formula or Approach:
No specific formula.
Need to know aflatoxin binders.
Step 3: Detailed Explanation:
Hydrated calcium aluminosilicate (HSCAS) has high affinity for aflatoxins.
It is a widely used binder.
DOT is an anticoccidial drug.
Activated charcoal has lower affinity.
MOS is a prebiotic.
Thus, HSCAS has high affinity.
Step 4: Final Answer:
HSCAS has high affinity for aflatoxins.
Hence, the correct option is (B).
