Many control and eradication programs have a program where herds that meet certain testing and monitoring standards can receive
a special status (e.g., Certified Brucellosis-Free herds, Scrapie Export Monitored Category). What is an advantage of such a status for the herd owner? a) The animals no longer need to be tested
b) The owner can freely add additional animals to the herd without restriction
c) The animals can generally move (interstate or internationally) with less testing
d) The herd is exempt from disease control regulations in other states
