Answer 1

yourObject.data[0].find(item => item.id === id_your_looking_for).checked = "true"

Ofc, you can wrap it in function and add a check if item is found, but i'm leaving it up to you:)

Answer 2

As you said, you will be checking on based some id. I have added one variable as chkID to check with sub_cat parent_id . you can check as per your requirement.

let chkID =1;
data.map(res => res.sub_cat.find((subItem) =>{ if(subItem.parent_id==chkID){
             subItem.checked = true;
             }}))
