Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.476% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a C=CCOc1ccc(Br)cc1/C=N/O
b CCOCCCNCc1ccc(OCc2ccccc2Cl)cc1
c O=C(COc1ccc(/C=N/NC(=O)c2cc3ccccc3o2)cc1Br)Nc1ccccc1
d COc1ccc(C(=O)Nc2ccc(N3CCCC3)cc2)cc1OC
Answer: a. C=CCOc1ccc(Br)cc1/C=N/O
