Filtrate in the Bowman’s capsule contains vitamins because

Filtrate in the Bowman's capsule contains vitamins because they have a low molecular weight. Vitamins are organic compounds that the body needs in small amounts to maintain normal physiological function. Due to their small size and molecular weight, they can easily pass through the glomerulus and into the Bowman's capsule during filtration in the kidney. Once in the filtrate, vitamins can be reabsorbed into the bloodstream and utilized by the body, or excreted in the urine if they are present in excess. Therefore, the correct option is "they have low molecular weight".
