<h2>Hello!</h2>
The correct answer is:
Es raro que ellos no hicieron los preparativos para la fiesta.
It's unusual that they did not do the preparations for the party.
<h2>Why?</h2>
First, we need to know with which person we are working, in order to conjugate the verb that we are using "Haber" (to have)
The Spanish person we have here is: They (Ellos)
It's a sentence talking about an action that "they" haven't done.
The correct conjugation for the verb "Haber" for this particular case is "hicieron"
Have a nice day!

The answer for this would be "Mi mamá, me lo trae".
