Try like this.

var app = angular.module("app",[]);

app.controller('MainCtrl', function($scope) {

  $scope.data = [{"1":"B"},{"5":"A"}];
  
  $scope.getData = function(){
     var d = {};
     angular.forEach($scope.data,function(value,key){
       for(var v in value){
        d[v] = value[v];
       }
    });
    return d;
  }
  
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="MainCtrl">
 <select ng-model="sel" ng-options="key as value for (key , value) in getData()"></select>
</div>
