Hope they will helped!
Always better to active child theme because if in future you update the parent theme to keep theme uptodate then your custom work in child theme will keep safe. So, you will need to install both parent and child theme and active child theme and do all custom work in child theme.
Thanks for your help! I chose the child theme.
