I have:
sda
and sdb
which partitions is forming mirror RAID
md0
md1
md2
md3
During update process, I was prompted where to install GRUB boot loader - on sda, sdb, md's or all together?
What choice is correct?

Recommended way would be to install grub to a master boot record on each hard drive, that is sda
and sdb
.
That way if one hard drive fails you will be able to boot from another one.
Depending on your setup sometimes you may need to install grub to a specific partition rather than a master boot record. For example if you have another boot loader sitting on the master boot record and want to install grub to a partition then choose one of the md
devices.
Similarly on EFI systems you should install grub to EFI system partition on both hard drives.
