Answer:
The correct answer is A.
A. Don't eat that cheese! There are plenty of other foods to choose from.
This is the correct answer choice. Don't is a combination of do not. The two word are mashed together and there is an apostrophe in the place that they were combined.
B. Don't eat that cheese! There are plenty of other food's to choose from.
This answer choice is incorrect because foods doesn't show ownership, and it is also not two words mashed together. It's just the plural of food.
C. Dont eat that cheese! There are plenty of other foods to choose from.
This answer choice is incorrect because don't is a combination of the words do not, and should therefore have an apostrophe.
D. Don't eat that cheese! There are plenty of other foods' to choose from.
This answer choice is incorrect for the same reason as answer choice B. Foods does not need an apostrophe anywhere.
