JSON validation using no schema or library

I have to validation my input of json data. So the input object will be like

components: {["A","B","C","D","E"]};

so i have to validate some cases here. well i have passed those cases i need to know is there any better way out here.

so the logic is :

• first element can only include A,B,C
• second can only include D, E
• third can only include F,G,H
• fourth can only include I,J
• fifth can only include K,L

function validationInput(obj){
    // logic
    // it must have 5 inputs and include one of each
      // A or B or C
      // D or E
      // F or G or H
      // I or J
      // K or L

      // if A exist then check if B and C doesnt
           // then check D or E exist then check it must doesnt exist other
               // then check or parts toooo......
    const arr = obj.components.sort();
    console.log(arr);
    if(arr[0] === "A" || arr[0] ==="B" || arr[0] ==="C"){
        console.log("pass1");
        if(arr[1] === "D" || arr[1] ==="E"){
            console.log("pass 2");
            if(arr[2] === "F" || arr[2] === "G" || arr[2] === "H"){
                console.log("pass 3");
                if(arr[3] === "I" || arr[3] === "J"){
                    console.log("pass 4");
                    if(arr[4] === "K" || arr[4] === "L"){
                        console.log("pass 5");
                        return true;
                    } else return false;
                } else return false;
            } else return false;
        } else return false;
    } else  return false;
};

After Suggestion

function validationInput(obj){
    const arr = obj.components.sort();

    if(arr[0] !== "A" && arr[0] !=="B" && arr[0] !=="C") return false;

    if(arr[1] !== "D" && arr[1] !=="E") return false;

    if(arr[2] !== "F" && arr[2] !== "G" && arr[2] !== "H") return false;
    
    if(arr[3] !== "I" && arr[3] !== "J") return false;
            
    if(arr[4] !== "K" && arr[4] !== "L") return false;
                        
    return true;
};
