Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.761\% 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 additional words.
Options:
a CCOC(=O)[C@H](CCc1ccccc1)N[C@@H](C)C(=O)N1CCC[C@H]1C(=O)O.O=C(O)/C=C\C(=O)O
b C=CCNc1cnn(-c2ccc(C)cc2)c(=O)c1Sc1ccc(C)cc1
c Cc1cc(C)nc(SCC(=O)c2ccc(O)c(O)c2)n1
d O=S(=O)(c1cc(Cl)ccc1Cl)n1nnc2ccccc21
Answer: d. O=S(=O)(c1cc(Cl)ccc1Cl)n1nnc2ccccc21
