Approach Solution -2
Elimination by mouthpart orientation:
Hypognathous mouthparts point downward from the head, typical of chewing insects feeding on a surface below them, not active hunters. Opisthognathous mouthparts point backward and downward, seen in sucking insects that feed while resting in place. "Opisthorhynchous" is not a standard recognised mouthpart orientation used to describe predatory insects. Only forward-projecting, prognathous mouthparts let an insect seize prey directly in front of it while chasing, which is essential for actively pursuing predators such as ground beetles and tiger beetles.
Hence, the correct answer is prognathous mouthparts.
