The C stocks can serve virtually all of the District Line - not just

They only have the Wimbleware part of the District on their line

Yes, as that is normally the only part of the District Line they serve
(technically C77s rather than C69s).

C77s were introduced to allow C stock to cover that bit of the
District, but there was never any separation of fleets. The first C
stock on the District was C69, and the first C77 stock went into
service on the Hammersmith.
