B Correct answer
Explanation

Glucose is the primary form of sugar absorbed into human blood from the digestive tract. During digestion, complex carbohydrates (starch, sucrose, maltose) are broken down into glucose by enzymes. Glucose then enters bloodstream through intestinal walls via active transport and diffusion. Sucrose (option A), maltose (option C), and starch (option D) are too large to be absorbed directly - they must first be converted to glucose.
