In persons suffering from insulin-dependent diabetes, _____ the cells of pancreas are degenerated.
The correct option is A Beta
Type 1 diabetes mellitus, also known as insulin-dependent diabetes, is believed to be caused by an auto-immune mediated destruction of the insulin-producing beta cells in the body. The destruction of these cells reduces the body's ability to respond to glucose levels in the body, therefore making it nearly impossible to properly regulate glucose and glucagon levels in the bloodstream. So, the correct answer is 'Beta'.
