Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.707\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1ccc(N2C(=O)C3C4C=CC(C4)C3C2=O)c([N+](=O)[O-])c1
b. Cc1c(C(=O)Nc2ccccn2)oc2ccccc12
c. N#Cc1c2n(c3c(=O)n(CC(=O)c4ccc(Br)cc4)cnc13)CCCC2
d. COc1cc(C(=O)Nc2ccc(S(=O)(=O)NC(C)(C)C)cc2)cc(OC)c1OC
Answer: a. COc1ccc(N2C(=O)C3C4C=CC(C4)C3C2=O)c([N+](=O)[O-])c1
