If LINQ is an option you could use:
            String[] filtered = (from item in QuetionOptions.AsQueryable()
                                 where item != null
                                 select item).ToArray();

Open in new window

if linq is not an option then do the following
List<string> result = new List<string>
for(int j = 0; j < QuetionOptions.length; j++)
{
    if(QuetionOptions[j] != null)
        result.add(QuetionOptions[ji]);
}
//you now have a list with no nulls if you specifcally want an array then do the following as well:
string[] resultArray = new string[result.count]
int j = 0;
foreach(string data in result)
{
    resultArray[j] = data ;
    j++;
}
