Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.814\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(O)C1C2CCC(C2)C1C(=O)Nc1cc(F)ccc1F
(b) O=C(Cc1ccccc1)c1c[nH]c(C(=O)C(Cl)(Cl)Cl)c1
(c) O=C(COc1cccc(-n2cnnn2)c1)Nc1ccccc1
(d) CCN(CC)CCCNC(=O)Cc1c(C(=O)O)n(C)c2ccccc12
Answer: c. O=C(COc1cccc(-n2cnnn2)c1)Nc1ccccc1
