Hi Crescent

They are the same swatches but the mode changes depending on if you are using vector objects or painting with pixels.

When used for vector objects:

A (Stroke) is the path around the outside of a vector shape or the colour of a drawn line.

B (Fill) is the inside fill of the vector shape.

When you are painting with pixel brushes:

C is the Foreground colour,

D the background colour.

The main purpose of the two (Foreground and background) swatches is to give you a choice while painting. You can press a keyboard shortcut (X) to swap focus between the two colours and the brush paints with that chosen colour. This is also very helpful if you are modifying a mask, because you will paint with white or black paint to add to or remove from the mask. You would therefore have one colour set in white, one in black and press X to swap between the two.

Foreground or background also defines what colour is used if you use the Edit > Fill option (from the Edit menu) to fill a pixel selection with colour. You have the choice of filling with Foreground or Background colours. This relates to the Foreground or background swatches.

p.s. I would recommend that you change your user name so spammers can’t get hold of it so easily.
