Task: Answer the multiple choice question.
Question: Which compound exhibits a 10.622\% 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, c, or d without using any other words.
Options:
(a) COc1ccc(-c2c[nH]c(=O)[nH]c2=O)cc1OC
(b) COc1ccccc1C(=O)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
(c) O=C(C[n+]1cccc(C(=O)N/N=C/c2ccc(Br)cc2)c1)c1ccccc1
(d) Cc1cc(C)c(-n2nnnc2SCC(=O)c2cccs2)c(C)c1
Answer: a. COc1ccc(-c2c[nH]c(=O)[nH]c2=O)cc1OC
