Explanation
Biodiesel beats petrodiesel on sulphur, carbon monoxide, lubrication and particulate emissions.
Statement 1 is right as biodiesel contains virtually no sulphur.
Statement 2 is right since it emits substantially less carbon monoxide.
Statement 3 is right because it lubricates engine parts better than petrodiesel.
Statement 5 is right as its particulate emission is much lower, while Statement 4 is wrong since biodiesel tends to emit slightly more, not less, oxides of nitrogen.
Biodiesel is made by transesterifying vegetable oils or animal fats.
