Ember dropdown selenium xpath

How to write xpath for the ember dropdown.

<ul id="ember-power-select-options-ember2473" class="ember-power-select-options ember-view" aria-controls="ember-power-select-trigger-ember2473" role="listbox"> <li class="ember-power-select-option" aria-selected="false" aria-current="false" data-option-index="0" role="option">Option A

Since the ember id changes, how can i write xpath??
