I am trying to merge unallocated space to drive c but unfortunately not able to do so. The drive c option is not showing extend option.

You can't modify the system partition because (as @Synetech commented) Windows locks the C: partition while you're booted into it.
In order to work with the partition you would need to either:
- Boot into another OS if you have one installed on a different partition, or
- Use a third party bootable tool. I used EaseUS Partition Master Free Edition, and it worked quite nicely.
A word of caution, if you do a lot of moving around, it's possible you may corrupt or otherwise break the MBR. Fixing this requires booting into a command prompt and executing bootrec /fixmbr
or bootrec /rebuildbcd
. A simple extension of the C: partition should not cause this, though.
The drive c option is not showing extend option.
That’s because Windows will not let you mess around with the system drive. You will need a third-party partition-management program to do that.
