Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 23.231\% 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 other words.
Options:
(a) O=C1OC(c2ccc(Br)cc2)=N/C1=C\c1ccco1
(b) OCC1CCCN(c2ncnc3scc(-c4ccccc4)c23)C1
(c) COc1cc2ccccc2cc1C(=O)NC(=S)Nc1nnn(C)n1
(d) CCOc1ccc(C(=O)Nc2ncn[nH]2)cc1
Answer: a. O=C1OC(c2ccc(Br)cc2)=N/C1=C\c1ccco1
