Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.112\% human ether-à-go-go related gene (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 additional words.
Options:
a) COc1ccc(NC(=S)N(CCCN2CCCC2)Cc2cccn2Cc2ccc(Cl)cc2)cc1Cl
b) COc1cccc(NC(=O)N2CCN(c3cccc(C)c3)C(C)C2)c1
c) CCC(C)[C@H]1CN=C(N)N1CCc1cccc2ccccc12
d) CC1(C)CN=C(NCc2ccccc2Cl)S1
e) O=C(c1cc2cc(Cl)ccc2[nH]1)N1CCN(c2ccccc2F)CC1
Answer: b. COc1cccc(NC(=O)N2CCN(c3cccc(C)c3)C(C)C2)c1
