"Extend Volume" option on C greyed out. Free space available but how?

I deleted a partition I had added previously for a Linux OS. After deleting it turned green as in "Free Space" I want that available space given back to C. I have included a screen shot of where I am. I don't know what to do next. The "Extend Volume" Option in C is not activated.

System info included below

Thank you.

Thank you for that partitionwizard resource AddRAM

Thank you AddRAM and thanks to older posts on this same issue, I am back to normal.

@gdcgray,
I can't figure out why you can't extend your system partition with disk management. "extend volume" greyed out mostly because that the unallocated space is not very behind system partition; but yours are.
Anyhow, glad to hear that you have solved your problem!
