Pqservice is the Acer hidden partition that contains the ISO to restore the pc back to factory original condition. System reserved is the Windows cab files for a Windows restore, that doesn't erase all your data.
If you never want to ever do a full factory restore back to brand new, and wipe out all your data, I don't see why you'd need to clone pqservice.
From the looks of that pic, you have a 1Tb hdd, that's partitioned into 4 parts, 500Gb in 1 partition, 490Gb in C: partition, and 10Gb in reserved partitions. Considering you have unallocated space, this wasn't done by a software install, like a Windows install, but manually done. The problem lies with how a bit and byte are computed, what most consider a kilobyte (1Kb) to a computer is 1024 bytes. Partitioning manually sometimes screws this up, so you get leftover space, which is unformatted, unallocated space.
MBR is basic master boot record and has been around for years. Perfectly fine for a 1Tb drive or lower. GPT is a Globally Unique Identifier (GUID) Partition Table. Works basically the same as MBR except for 2 major differences. MBR will allow up to 4 partitions, GPT 128, and MBR keeps its partition table info all in 1 place, GPT keeps its partition table info at the end of each partition. GPT is designed more for very large hdd where more than 4 partitions are needed, but works either way.
Both can be basic or dynamic, basic is easy to work with, dynamic has more security options and needs more than the freeware version of any clone software to enable cloning. Do not choose dynamic, its basically a pain in the ash.
I use MiniTool partition wizard free, I found it easier than ease us todo, and I went all through the fans, help etc because before cloning, I had a dynamic Drive with 4 partitions. Converting that to basic MBR is not something I ever want to do again, ever.
You will have 3 real choices. Copy disc does just that, copy. What it doesn't so is set your destination as an active boot drive, basically it's making a perfect backup that won't try to interfere with your current boot preferences. That's what clone is for. Last choice is migrate OS, which pretty much sets up windows without your data on a new disc. This is basically for making a fresh install on a new disc when you don't have an install CD or USB ISO that's usable. This leaves you stuck with cloning.
