M201: Lab2.1 - Detailed answer for the one of the options

I was able to solve the lab but I’ve a doubt regarding the detailed answer for one of the options. A query was using the prefix used in creating the index, but the solution for it stated that it failed to use equality on the index prefix. Could someone explain what does it mean by this.

Thank you in advance.
