Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.890\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CC(=O)Nc1ccc(O)c(-c2nc3ccccc3s2)c1
b. C=CCOc1c(Br)cc(/C=N/n2c(CC)n[nH]c2=S)cc1Br
c. CCCNC(=O)NC(=O)CSc1nc2ccccc2n1CC(C)C
Answer: a. CC(=O)Nc1ccc(O)c(-c2nc3ccccc3s2)c1
