You Can get Ur Desired Value simply like this..

let checkId = 2;
let data = {
    "1": {
        "Increase": true,
        "Decrease": true,
        "Like": true,
        "Dislike": true,
        "Old": false,
        "Others": true
    },
    "2": {
        "Increase Again": true,
        "Decrease Previous": true,
        "Like": true,
        "Dislike": true,
        "Old Again": false,
        "Others": true
    },
    "3": {
        "Increase Previous": true,
        "Decrease Prior": true,
        "Like": true,
        "Dislike": true,
        "Old": false,
        "Others Check": true
    }
}
let result = data[checkId]
console.log(result)

You can simply get the specific element by passing the checkId in your response, For instance I'm assuming that you have that JSON in result variable.

You can call it in the following way

 let result = //Your json;
 let checkId = 2;
 result[checkId] ==> This will return 2nd object of JSON
