d. both a and b are correct.

The answer is: A) The social cost of producing good X includes the private cost plus the cost to bystanders of the externality.

Explanation:

Negative externalities are costs suffered by third parties as a consequence of producing a certain product or service. Negative externalities are caused by the consumption of products, but the third parties damaged are no involved in the buyer-seller transaction. Social costs include production costs plus negative externalities.
