Identify the correct choice He has purchased a bag of ____________

Answer: flour

Explanation:

• flour: A powder made from grains used in cooking and baking; it is commonly sold in bags, so "a bag of flour" is natural and correct.

• floor: The surface you walk on inside a building; you would not say "a bag of floor." This meaning does not fit the sentence.

• flower: A blossom. While people buy flowers (often as a bouquet or bunch), "a bag of flowers" is an unusual phrasing and does not fit the typical usage here.

• flaur: Not a correct spelling or English word; likely a misspelling of "flour."

Therefore, the sentence correctly reads: "He has purchased a bag of flour."
