The window’s right side displays your disk drives and their partitions. Your C partition is identified by the characters “(C:)”, along with the words “System,” “Boot File,” “Page File,” and other technical verbosity. (It also has a blue line across its top.)

So, your mission is to extend your C partition’s boundaries to grab that unused space.
