Task: Answer the multiple-choice question.
Query: Which compound exhibits a -9.928\% 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(NCc1n[nH]c(=O)c2ccccc12)C1CC(=O)N(c2ccc(Cl)cc2)C1
(b) Cl.O=C(Oc1cccc2cccnc12)c1cccs1
(c) O=C(N/N=C/c1ccc(-c2cccc(C(F)(F)F)c2)o1)c1ccccc1O
(d) C#CCN(CC=C)C(=O)C1CCC(=O)N(CCCc2ccccc2)C1
Answer: a. O=C(NCc1n[nH]c(=O)c2ccccc12)C1CC(=O)N(c2ccc(Cl)cc2)C1
