Which of the following munitions can the MQ-9 carry?

The MQ-9 Reaper is designed for both surveillance and precision strike missions, making it capable of carrying various munitions. The inclusion of GBU-12 Paveway II bombs and Hellfire missiles reflects its intended role as an effective platform for engaging ground targets. The GBU-12, a laser-guided bomb, is designed for precision strikes, while Hellfire missiles are specifically developed for anti-armor and precision targeting. This combination enhances the MQ-9's versatility and effectiveness in various combat environments.

Other options suggest munitions or equipment that do not align with the operational capabilities of the MQ-9. Conventional hand grenades are not typically mounted on unmanned aerial systems designed for strike operations. The mention of only surveillance equipment ignores the dual-role nature of the MQ-9. Finally, aircraft cannon rounds would require a traditional fighter or attack aircraft, as the MQ-9 does not possess an internal cannon and is designed for missile and bomb delivery rather than cannon fire.
