Lactobacillus delbrueckii is a beneficial bacteria found in the digestive tract. The proper balance of gut flora helps to keep your intestinal walls strong and bad bacteria at bay and can reduce the risk of chronic disease. which are highly adapted to growing on lactose and converting it into lactic acid.

Alimentary canal is also called as digestive tract. It starts in the mouth followed by buccal cavity and ends at the anus. The digestion starts in the anterior cavity called buccal cavity. Teeth are embedded in a socket of mandible (lower jaw) and maxilla (upper jaw). These sockets are called as tooth sockets. Human shows both diphyodont and monophyodont types of dentition. In diphyodont dentition, there are 2 sets of teeth, namely deciduous and permanent set. In monophyodont dentition, there is only 1 set of teeth. In humans, molar teeth show monophyodont dentition and rest teeth show diphyodont dentition. Pharynx is part of both digestive and respiratory system. Pharynx opens into oesophagus in digestive system and larynx in respiratory system. 

Esophagus, colon and rectum are studied with the T.S. of the gut. They are all a part of the digestive system where is wearing is a part of the digestive as well as the respiratory system and it is not studied along with them.

It begins in the stomach by pepsin which breaks down the peptide bind and makes protein smaller for easier digestion. Trypsin and chymotrypsin are also enzymes that are created by the pancreas and will cut down proteins into small peptides. 

All of these choices are a part of your digestive system. Your digestive system has many other associated organs including the small intestine, large intestine, and liver. The stomach is an area of food digestion. The pancreas releases hormones, that affect the digestive process. The rectum is the last place you store you food before the process of elimination (pooping).

The pharynx connects the mouth to an area in your throat with a flap. The flap is the epiglottis. The flap moves to one side for food and the other side as you breathe. The branching point leads to the larynx or the esophagus.

The alimentary canal of grasshopper is divided into three main portions as

• Foregut
  
• Midgut
  
• Hindgut
  

Foregut consists of mouth surrounded by the mouth-parts.
Midgut consists entirely of stomach or ventriculus.
Hindgut is a coiled structure consisting of anterior ileum, middle colon and posterior is rectum.
Therefore, the correct answer is option B.
