Option 1 -> Virtuous means having high moral standards, but doesn't relate to being cheerful and animated.
Option 2 -> Vivacious means lively, energetic, and full of enthusiasm, which perfectly matches the description.
Option 3 -> Versatile means adaptable or multi-skilled, which doesn't fit the context of animating a room.
Option 4 -> Valiant means brave or courageous, which is unrelated to cheerfulness and charm.
Hence, Option 2: Vivacious -> The word "vivacious" directly describes someone who is lively, animated, and full of high spirits, which aligns perfectly with Veena's "cheerful and free-spirited presence" that "animated the room and charmed everyone." -> correct
