Use the following

setTimeout(function () {
    chart.internal.expandArc(['A', 'B'])
}, 0)

Note: The ideal solution would be to grab the mouseover callback and call it with your data but if you only want to expand the arcs just call the method above

var currentSlice;

var chart = c3.generate({
  bindto: '#dash',
  data: {
    x: 'x',
    columns: [
      ['x', '2013-01-01', '2013-01-02', '2013-01-03', '2013-01-04', '2013-01-05', '2013-01-06'],
      ['A', 30, 200, 100, 400, 150, 250],
      ['B', 130, 100, 140, 200, 150, 50],
      ['C', 50, 100, 130, 240, 200, 150],
      ['D', 130, 100, 140, 200, 150, 50],
      ['E', 130, 150, 200, 300, 200, 100]
    ],
    type: 'donut'
  },
  axis: {
    x: {
      type: 'timeseries',
      tick: {
        format: '%Y-%m-%d',
        centered: true,
        position: 'inner-right'
      }
    }
  },
  bar: {
    width: {
      ratio: 0.5 // this makes bar width 50% of length between ticks
    }
  },
  tooltip: {
    grouped: false,
    contents: function(data, defaultTitleFormat, defaultValueFormat, color) {
      //  console.log("Containt");
      // console.log(data, defaultTitleFormat, defaultValueFormat, color);
      return "
" + data[0].value + "
";

    }
  }
});
setTimeout(function() {
  chart.internal.expandArc(['A', 'B'])
}, 0)
