Answer 1

  in html---->

     
        
          
             {{q}}
            
        
      


in ts---->
//if u dont want any default selection
    this.defaultSelectQuestion = -1; 

//if first element should be your default selection
  this.defaultSelectQuestion = 0;



this.selectedQuestion=this.questionArray[this.defaultSelectQuestion]
