Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.664\% 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) CC(C)c1nc(SCC(=O)NCC2CCCO2)c2c(=O)n(C)c(=O)n(C)c2n1
b) Brc1ccccc1Cn1c(-c2cscn2)nc2ccccc21
c) O=c1c(Cl)c(N2CCN(S(=O)(=O)c3ccc(F)cc3)CC2)cnn1-c1cccc(Cl)c1
d) O=C(NN=C1c2ccccc2-c2ccccc21)c1ccccc1
e) COc1ccc(/C=C2\SC(=S)N(N3C(=O)CCC3=O)C2=O)cc1O
Answer: c. O=c1c(Cl)c(N2CCN(S(=O)(=O)c3ccc(F)cc3)CC2)cnn1-c1cccc(Cl)c1
