Hint:We Know that gastric acid is a stomach related liquid framed inside the stomach lining. Made out of hydrochloric corrosive, potassium chloride, and sodium chloride, gastric corrosive assumes a critical function in processing of proteins by enacting stomach related compounds, which together separate the long chains of amino acids of proteins. Gastric corrosive is controlled in criticism frameworks to build creation when required, for example, after a feast. Various cells in the stomach produce bicarbonate, a base, to pad the fluid, ensuring regulated \[pH\].

Complete step by step answer:
We have to remember that the primary constituent of gastric corrosive is hydrochloric corrosive created by parietal cells in the gastric organs in the stomach. Its discharge is a complex and generally vigorously costly cycle. Parietal cells contain a broad secretory organization from which the hydrochloric corrosive is discharged into the lumen of the stomach. The pH of gastric corrosive is 1.5 to 3.5 in the human stomach lumen, a level kept up by the proton siphon\[{H^ + }/{K^ + }ATPase\]. The parietal cell discharges bicarbonate into the circulation system all the while, which causes an impermanent ascent of pH in the blood, known as an antacid tide.
We need to know that the acid which is normally found in the gastric juices of the stomach is hydrochloric acid. The gastric juices, together chloride, or potassium chloride, and sodium chloride. As hydrochloric corrosive is quite a firmly destructive substance, it just makes up around 5 percent of the creation of gastric corrosive. This gives gastric acids low pH range, as a rule between 1 to 2.
Hence option A is correct.

We must remember that the profoundly acidic climate in the stomach lumen makes proteins from food lose their trademark collapsed structure. This uncovered the protein peptide bonds. The gastric boss cells of the stomach emit chemicals for protein breakdown. Hydrochloric corrosive activates pepsinogen into the compound pepsin, which by then helps retention by breaking the amino destructive bonds, a cycle called proteolysis. Likewise, various microorganisms are stifled or obliterated in an acidic atmosphere, preventing infection or disorder.
