Task: Answer the multiple-choice question.
Query: Which compound exhibits a -1.924\% 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, or c without using any other words.
Options:
a) CC(=O)NC(c1ccc(F)cc1)c1cccnc1
b) O=C(CCCc1ccccc1)Nc1ccnn1C1CCN(Cc2ccc(Cl)cc2)CC1
c) O=C(NCc1ccncc1)Nc1cccc(Cl)c1
Answer: c. O=C(NCc1ccncc1)Nc1cccc(Cl)c1
