Task: Answer the multiple choice question.
Question: Which drug has a 17.955\% 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, or d without using any other words.
Options:
a O=C1CCN(Cc2ccc(Br)cc2)CCN1[C@H](CO)c1ccccc1
b COc1ccccc1N(CC(=O)N/N=C/c1ccc(OCC(=O)NCc2ccco2)cc1)S(=O)(=O)c1ccc(C)cc1
c O=C(O)c1cccc(S(=O)(=O)N2CCN(c3ccccn3)CC2)c1
d COc1ccc(-c2cc3ncnc(Cl)c3s2)cc1
Answer: d. COc1ccc(-c2cc3ncnc(Cl)c3s2)cc1
