As Mike state, your explanation sounds as if you want to make Drive 0 and
Drive 1 seen as a single drive.

You can only extend a partition into unallocated space. This prevents
extending Partition D: into C:. You can't really remove C:, but it can be
shrunk somewhat.
Resize C: to minimum it allows.
Extend D: to reclaim unallocated space.

Alternatively:
Partition Disk 2 as a Simple Partition.
Copy all important data from D: to Drive 2, then remove the D: partition.
Extend C: partition to encompass all of Drive 0.
