Task: Answer the multiple choice question.
Question: Which compound has a 13.440\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(Cc1cccs1)NCCc1cn2ccccc2n1
b: CCc1ccc(Oc2cc(C)nc(N)n2)cc1
c: O=C1Nc2ccccc2S/C1=C/c1cccs1
d: CCCC(=O)Nc1nc2ccc(S(N)(=O)=O)cc2s1
e: CCC1CN(C(=O)N2CCC(C(=O)NCc3cc(OC)c(OC)c(OC)c3)CC2)c2ccccc2O1
Answer: c. O=C1Nc2ccccc2S/C1=C/c1cccs1
