The question is asking how the digestive function of the rumen in ruminant nutrition is enhanced. The rumen is a large fermentation chamber in the stomach of ruminant animals like cows and sheep. It plays a crucial role in the digestion of plant material.

The correct answer is Option B: Presence of micro-organisms.

The rumen is home to a diverse community of microorganisms, including bacteria, protozoa, and fungi. These microorganisms have a symbiotic relationship with the ruminant animal. They help break down complex carbohydrates, such as cellulose and hemicellulose, into simpler compounds that the animal can absorb and use for energy.

The microorganisms in the rumen produce enzymes that can break down plant material that the ruminant's own digestive enzymes cannot. This allows the ruminant to extract more nutrients from the plant material it consumes.

In addition to aiding in the digestion of plant material, the microorganisms also produce volatile fatty acids, which are an important energy source for the ruminant. The volatile fatty acids are absorbed through the rumen wall and provide a significant portion of the ruminant's energy needs.

Therefore, the presence of microorganisms in the rumen is essential for enhancing the digestive function of the rumen in ruminant nutrition.
