Task: Answer the multiple-choice question.
Question: Which compound exhibits a 17.390\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a) CN(CC1COc2ccccc2O1)C(=O)c1cccc(S(=O)(=O)N2CCCC2)c1
b) O=C(NCCN1CCN(Cc2ccccc2)CC1)c1ccc(CS(=O)(=O)c2ccc(Br)cc2)o1
c) O=c1oc(-c2cccs2)nc2ccc(Cl)cc12
d) COc1ccc(C2=NN(c3nc(-c4ccc(CNC(C)=O)cc4)cs3)C(c3ccco3)C2)cc1
e) CCCNC(=O)N1[C@H]2CC[C@@H]1C(C(=O)OC)=C(c1ccc3ccccc3c1)C2
Answer: c. O=c1oc(-c2cccs2)nc2ccc(Cl)cc12
