[HTML] Default select option?

Ok so I have a tradiotional select form:


<form> 
Example:
<select name="Example" onchange="example(this.value)">
<option value="1">option 1
<option value="2">option 2
<option value="3">option 3
</select>
</form>


My question is how do I set a deafult option as when I click on option 2 then refresh the page or anything it now starts on op[tion 2, any help?
