○ d. the sentence is correct as it is.

Explanation:

Question 1

In a series of three or more items, commas are used to separate each item, including before the "and" (Oxford comma). The original sentence lacks commas between the items. Option a correctly places commas between "apples", "bananas", and before "and oranges". Option b misses a comma after "apples", option c incorrectly places a comma after "oranges", and option d is wrong as the original sentence needs commas.

When a dependent clause (starting with "Since") introduces an independent clause, a comma is used after the dependent clause. Option c correctly places a comma after "tomorrow" to separate the dependent and independent clauses. Option a incorrectly places a comma after "Since", option b incorrectly places a comma after "plan", and option d is wrong as the original sentence needs a comma.

Answer:

a. I bought apples, bananas, and oranges at the supermarket yesterday.
