Explanation:
Detailed explanation-1: -Plasma proteins have a higher molecular weight and is thus inhibited by the basement membrane of the glomerular capillaries from being filtered out. Hence, plasma protein is the least likely to be found in the glomerular filtrate.
Detailed explanation-2: -Protein is present in the blood; healthy kidneys should only filter tiny (trace) amounts into the urine as most protein molecules are too large for the filters (glomeruli). It is not usual to lose protein in the urine.
