The question on the earth fault loop path is asking for a diagram of a specific fault location.
This is presumably to avoid someone doing what you have asked about, just drawing the standard diagram, without actually reading the question in detail.
e.g. do you know what a distribution circuit is? this is where the fault has occurred.
Do you notice that it is a three phase supply?, etc.
I have just drawn these as an example, the top one may (possibly) be considered a standard TNS EFLP for TPN, the bottom one shows the EFLP as requested in the question (though I have selected L3 for the fault, it was just easier to draw!)
I think the standard way of drawing three phase is to show the supply lines coming in and then omit the non faulted distribution lines for clarity and you probably can just show the transformer as having three lines, neutral and earth and a nominal winding.
