Task: Answer the multiple-choice question.
Question: Which compound exhibits a 12.470\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCc1[nH]nc2c1C(c1ccsc1)C(C#N)=C(N)O2
b) COc1ccc(N2CC(C(=O)Nc3nc4ccc(F)cc4s3)CC2=O)c(OC)c1
c) O=C1CN(C(=O)c2ccc(Br)o2)C(c2ccccc2)c2cc(Cl)ccc2N1
d) CSc1ccc(/C=C/C(=O)N2CCCN(C)CC2)cc1.Cl
Answer: a. CCc1[nH]nc2c1C(c1ccsc1)C(C#N)=C(N)O2
