Final Answer:
Torbjorn says "Molten Core!" when he ults.
Thus the correct option is A.
Step-by-step explanation:
In the game Overwatch, each hero has a unique ultimate ability that is triggered by pressing a specific key.
For Torbjorn, when he activates his ultimate ability, he exclaims "Molten Core!" This catchphrase signals the commencement of his powerful ultimate move, where he upgrades his turret, grants additional armor to himself and nearby allies, and increases the fire rate of his Rivet Gun.
Torbjorn's ultimate, "Molten Core," is distinctive in its announcement, making it clear to both teammates and opponents that he's initiating a potent offensive or defensive play.
The voice lines associated with ultimate abilities in Overwatch serve both practical and thematic purposes, enhancing the gaming experience by providing auditory cues for significant in-game events and reinforcing each hero's personality and style.
In Torbjorn's case, "Molten Core!" aptly reflects the molten metal theme of his character and the fiery, upgraded nature of his turret during the ultimate.
Torbjorn says "Molten Core!" when he ults.
Thus the correct option is A.
