When looking at the ingredient label of a bottled spaghetti sauce, you see that olive oil is the second ingredient. This means that olive oil is ...

A. the second most abundant ingredient by volume.

B. the second most abundant ingredient by weight.

C. just one of the ingredients present in the sauce.

D. the second ingredient by alphabetical listing.

B. The second most abundant ingredient by weight.

Explanation:

The ingredients written in the ingredient label are written in ascending order of abundance present in that product. All the quantities written on the ingredient label are measured by weight.

So if the olive oil is written on the second number it means that the olive oil is the second most abundant ingredient in that product by weight.
