Explanation:

The question asks "how many seedlings were left to be planted?" so the answer is D.

The given facts are listed in the problem, 90 cabbage seedlings, 19 seedlings in each 3 rows.

You have to figure out how many seedlings are planted, which is 19 seedlings x 3 rows = 57 already planted. You then subtract that from total seedlings she has which is 90 - 57 = 33 seedlings left to be planted. This means you use multiplication AND subtraction so B.
