Which part of ruminants stomach resembles true stomach?

Answer: Option B

Abomasum part of ruminants stomach resembles the true stomach.
The abomasum is the “true stomach” of a ruminant. It is the compartment that is most similar to a stomach in a nonruminant.
The abomasum is the only compartment lined with glands. These glands release hydrochloric acid and digestive enzymes needed to break down feeds. The abomasum is similar to a nonruminant stomach.
