Task: Answer the multiple choice question.
Question: Which drug has a 16.296\% 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=c1[nH]c(=S)[nH]nc1Cc1ccccc1
(b) CCn1cc(C(=O)NCc2ccccc2Cl)cn1
(c) COc1ccc(CN2CCNC(=O)C2CC(=O)NCCN2CCCCC2=O)c(F)c1
(d) O=C(OCC(=O)c1ccc(Cl)s1)c1cnccn1
(e) CC(C)c1ccc(NC(=O)c2ccc(NS(C)(=O)=O)cc2)cc1
Answer: b. CCn1cc(C(=O)NCc2ccccc2Cl)cn1
