Task: Answer the multiple choice question.
Query: Which compound has a 1.933\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(/C=C/c1ccccc1)NCCc1nc2ccccc2[nH]1
(b) COc1cc2c(cc1NC(=O)/C=C/c1cc(OC)c(OC)c(OC)c1)oc1ccccc12
(c) CSc1nc2ccccc2cc1/C=C(\C#N)c1cccc(Cl)c1
Answer: a. O=C(/C=C/c1ccccc1)NCCc1nc2ccccc2[nH]1
