Assume that executives from competing producers of the two leading dog-food brands get together and decide to charge a certain price for their lamb and rice dog food. This would be an example of:
a. a vertical restraint of trade.
b. a horizontal restraint of trade.
c. a violation of the Clayton Act. d. a violation of an antitrust exemption.

b. a horizontal restraint of trade.

Explanation:
