Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.875\% 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(Nc1ccccc1Oc1ccsc1C(=O)O)c1ccccc1
b. C/C(=N/NC(=O)c1cccc(N2CCCC2=O)c1)c1ccc(Br)cc1
c. O=C(CSc1nc2ccccc2nc1N1CCCCC1)Nc1ccc(F)cc1
d. COc1cc(Cl)cc(C2NC(=O)NC(C)=C2C(C)=O)c1OCC(=O)O
e. CN(C)C(=O)c1nc(C#N)c(N(C)C)o1
Answer: a. O=C(Nc1ccccc1Oc1ccsc1C(=O)O)c1ccccc1
