I believe that the closest you can come across with a simple HTML solution is to disable this option:
<select> <option selected="selected" disabled="disabled">Choose option</option> <option>Option 1</option> <option>Option 2</option> <option>Option 3</option> <option>Option 4</option> </select>
Demo
The item will still be displayed in the list, but it will not be available, and it will not be possible to select from the drop-down list after it is opened.
