Hi Tanu,

I tested the this code in my org and invoked it in using execute anonymous.
There is no problem at all.Its working as expected.
Make sure you saved the class before checking challenge or excuting using execute anonymous.
Plase execute StringArray class un=sing below line in execute anonymous and see the debug log. 
Test.generateStringArray(5);​

Public Class  StringArrayTest
{
Public Static string[]  generateStringArray(integer index)
{

 List<String> moreColors = new List<String>();
  for(integer i=0;i<index;i++)
  { 
  moreColors.add('Test ' + i);
  }
 
    for(integer i=0;i<index;i++) 
 {
     
     System.debug(moreColors[i]);
 }
return morecolors;
}

}

Please let me know if it helps.
Thanks.
