Hi Sai,

try with below code.

trigger: 
trigger validation on Account (before insert) {
    
    If(trigger.Isbefore && trigger.Isinsert){
        TriggerhelperClass.PhoneFaxRatingValidation(trigger.new);
    }

}
Class: 
public class TriggerhelperClass {
    
    public static void PhoneFaxRatingValidation(List<account> acclist){
        
        for(account acc:acclist) {
            
            if(acc.Rating == Null || acc.Rating == ''|| acc.Fax == Null ||acc.Fax ==''||acc.phone == Null||acc.phone==''){
                acc.Rating.adderror('Please Select the Rating Value');
                acc.Phone.adderror('Please Select the Rating Value');
                acc.Fax.adderror('Please Select the Rating Value');

Hi Sai Kiran,

You can do this by using validation rule.
  
OR(ISBLANK(Phone),ISBLANK(TEXT(Rating)),ISBLANK(Fax))
