Which of the following operating activities is supported by digital mode software in the WSJT-X software suite?

The WSJT-X software suite, originally developed by Nobel laureate Joe Taylor (K1JT), contains a variety of digital modes engineered specifically for decoding signals that are often too weak to be heard by the human ear. This suite includes modes like JT65 and Q65 for Earth-Moon-Earth (moonbounce) communications, MSK144 for bouncing signals off brief meteor trails (meteor scatter), and WSPR (Weak Signal Propagation Reporter) for automated propagation beacons. Because WSJT-X contains specialized protocols designed to support all these unique weak-signal activities, 'All these choices are correct' is the proper answer.
