Task: Answer the multiple-choice question.
Question: Which drug has a -5.244\% 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=C(Cc1ccc(Cl)cc1Cl)Nc1ccncc1Cl
b O=C1c2ccccc2NC(c2ccccc2)N1Cc1ccco1
c CC1(C)Cc2ccccc2C(NN=C2CCCC2)=N1
d CN(C)c1ccc(-c2cc([C@H]3[C@@H]4C=CCC[C@@]4(C)C(=O)N3Cc3ccccc3)ccc2F)cc1
Answer: c. CC1(C)Cc2ccccc2C(NN=C2CCCC2)=N1
