Task: Answer the multiple choice question.
Query: Which compound exhibits a 19.828% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc(S(=O)(=O)NC2CC3CCC2C3)cc1Br
b C[C@@H]1NC(=O)c2cc([N+](=O)[O-])cc(I)c2NCC[C@@H](C(N)=O)NC(=O)[C@H](CCC(=O)O)NC1=O
c O=C(NNC(=S)NCc1ccco1)C(c1ccccc1)c1ccccc1
d O=c1[nH]c2ccccc2nc1-c1ccc(Cl)cc1
Answer: d. O=c1[nH]c2ccccc2nc1-c1ccc(Cl)cc1
