Task: Answer the multiple choice question.
Question: Which drug exhibits a -12.899\% 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) COc1ccc(-c2c(-c3ccsc3)oc(=O)c3cc(OC)c(OC)cc23)cc1
(b) C=CCN1C(=O)C(Cc2ccc(OCC)cc2)S/C1=N\N=C\c1cccs1
(c) CC(NC(=O)COC(=O)c1cc([N+](=O)[O-])ccc1N1CCOCC1)c1ccc(F)cc1
(d) COc1ccc(Oc2coc3cc(OC(=O)c4cncc(Br)c4)ccc3c2=O)cc1
Answer: c. CC(NC(=O)COC(=O)c1cc([N+](=O)[O-])ccc1N1CCOCC1)c1ccc(F)cc1
