Yes, this is true although it only applies to
multiple response questions that offer
four answer choices. Other multiple response questions will usually indicate "select three that apply" etc (actually A LOT of those on section 3 this August) so be aware of the difference. Multiple choice will only ever have one correct answer.
This tip has been confirmed by ASLA's prep webinar series. The LARE Prep exams are not affiliated with CLARB or ASLA hence why they do not adhere to the same response style.
Good luck!
