Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -1.097\% 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 additional words.
Options:
(a) COc1cccc(-c2[nH]nc3c2C(c2ccsc2)C(C#N)=C(N)O3)c1
(b) O=C(NCCc1ccncc1)Nc1ccccc1
(c) Cc1c2cn[nH]c(=O)c2c(C)n1Cc1ccc(F)cc1
Answer: b. O=C(NCCc1ccncc1)Nc1ccccc1
