The device at a is called a bayonet-mount spring tip. It is used on high frequency circuits because it
eliminates the long ground lead inductance and reduces ringing.
The tip at b allows the user to probe IC pins. The tip at c is for general-purpose probing and insulates
the tested circuit from the grounded band of metal. The adapter at d allows the probe to be plugged into
a BNC female connector. This makes for a convenient connection to test equipment and to BNC test
ports on circuits.
A common tip not shown in the picture is a sprung hook. This has a spring-loaded hook that can be
clipped over a wire. The spring helps hold the probe tip onto the wire.
Here's a picture of the end of the probe with the BNC male connector that plugs into the scope:

The hole in the plastic body is where you insert the small plastic screwdriver (supplied with the probe)
to adjust the probe's compensation.
Note the yellow band around the probe and the probe's end in Figure 37 and Figure 39. These are used
to help identify the probe when you have a number of probe connections (i.e., you don't have to trace
the wire from the scope to the probe tip). The probe comes with four pairs of colored rings.
