A
juxtaglomerular cells
B
macula densa
C
podocytes
D
fenestrations
Explanation: 

Detailed explanation-1: -Under normal conditions, high molecular weight proteins in the plasma (e.g., albumin and globulin) cannot pass through the filtration membrane due to the effects of the size barrier and charge barrier of the glomerular capillary filtration membrane.

Detailed explanation-2: -The podocytes have long foot processes called pedicels, for which the cells are named (podo-+-cyte). The pedicels wrap around the capillaries and leave slits between them. Blood is filtered through these slits, each known as a filtration slit, slit diaphragm, or slit pore.
