Answer: the correct option is D (There are no circumstances in which animal work may begin before IACUC approval)
Step-by-step explanation:
The IACUC known as Institutional Animal Care and Use Committees is a local working group that research facilities must appoint in accordance with the Animal Welfare Act , Policy on Human Care and Use of Laboratory Animals. It was introduced to research system by the U.S. government in 1986. The policy protects all warm-blooded animals except rats, mice, and birds bred for research. For an institution to use a specie that is covered by the policy, it must obtain their approval before work begins. I hope this helps. Thanks.
