Given: none of the products sold by Best Buy have a warranty

d. Some products not sold by Best Buy do have a warranty.

- There is no mention products sold by others (other than Best Buy) in main sentence. Hence, this is not sure

c. Everything that’s not a product sold by Best Buy has a warranty

- Best buy sells product,. Hence, there is nothing which is not a product and sold by Best buy

b. Nothing with a warranty is a product sold by Best Buy.

- Again invalid statement

a. Some products sold by Best Buy do not have a warranty.

- as none of the products sold by Best buy have a warranty, some products sold by Best Buy do not have a warranty is a valid statement.

Thus, correct answer is option a
