Answer: its (D) 0.72

Explanation:

Basically, the ones who shopped with a shopping list and bought only the expected items is 0.43 and row totals is 0.60. So what you do here is either calculate on your own or a easy option, you can just go on the internet, ( 0.43 out of 0.60 or 43 out of 60 ) and there will be answer 0.716666667 and then you just round it, like the question asked you and get 0.72
