Heavy infestation of liver fluke causes poor absorption of fats in livestock by

A.

Blocking bile ducts thus preventing flow of bile

B.

Destroying fat-digesting enzymes

C.

Reducing ingestion of fats

D.

Inhibiting the action of digestive enzymes

Correct answer is D

A liver fluke is a parasitic worm. After liver flukes have been ingested, they travel from the intestines to the bile ducts in the liver where they live and grow. They grow so much that they contaminate the bile and this affects fat-digesting enzymes.
