    Answer : Option C

    Explanation :

    -The spark ignition engines are governed by Quantitative governing. -SI engines being quantitatively governed by controlling the quantity of charge inducted, leading to high throttling losses. -To qualitatively govern the engine, charge purity was reduced by incorporating EGR, thereby reducing the amount of available oxygen in the charge inducted.
