Try like following snippet (you can create method and find selected option):

new Vue({
  el: "#demo",
  data() {
    return {
      text: "",
      selected: null,
      options: [
        { value: null, text: "Please select an option" },
        { value: "a", text: "This is First option" },
        { value: "b", text: "Selected Option" },
        { value: { C: "3PO" }, text: "This is an option with object value" },
        { value: "d", text: "This one is disabled", disabled: true },
      ],
    };
  },
  methods: {
    place() {
      if (this.selected) return this.options.find(o => o.value === this.selected).text
    }
  }
})
