Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.859\% 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) O=C(OCc1nnc(-c2ccccc2)o1)c1ccc(-n2cnnn2)cc1
(b) CCn1c(SCC(=O)Nc2ccc(C)cc2)nnc1-c1cnccn1
(c) Br.COc1ncnc2c1NC1=C(S2)C(=NCCC(=O)O)CC(C)(C)C1
Answer: a. O=C(OCc1nnc(-c2ccccc2)o1)c1ccc(-n2cnnn2)cc1
