Which ingredient provides dough with its strength and gas-retaining ability?

Explanation:
Gluten gives dough its strength and gas-retaining ability because when flour is hydrated and kneaded, two proteins—glutenin and gliadin—form a viscoelastic gluten network. This network stretches as gas bubbles rise during leavening, trapping the gas and providing the structure that lets the dough rise and hold its shape. Starch contributes bulk but doesn’t create the elastic, gas-trapping matrix; fat mainly affects tenderness and crumb, not the ability to hold gas; a general label like protein is too broad, since only gluten in wheat flour forms the specific network that provides that strength and rise.
