The primary reason for the absence of much litigation under foreign competition law is:

I. The preapproval process reduces the necessity for litigation.
II. Differences in the remedies and types of sanctions for violations.
III. Cultural attitudes toward antitrust law differ.

a. I only.
b. II only.
c. III only.
d. I and I. I, II, and III.

III only.

Cultural attitudes toward antitrust law differ.

Explanation:

Competition law is an area of law that seeks to maintain a level playing field for all participants in an industry by protecting them against anti-competitive conduct by companies.

For example two major players in an industry may collaborate to raise price of goods.

However in foreign competition law we have to consider that cultural attitudes towards antitrust law differs. What is accepted in one country may not apply in another. So there is absence of litigation when considering competition in the foreign scene.
