Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 15.087\% 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 additional words.
Options:
(a) O=C1C2CC=CCC2C(=O)N1c1ncn[nH]1
(b) O=C(N/N=C/c1ccc(Cl)cc1)Nc1ccccc1
(c) O=C(COC(=O)c1cccc(Br)c1)NCCc1ccc(F)cc1
(d) CCCCCc1nnc(N)s1
Answer: a. O=C1C2CC=CCC2C(=O)N1c1ncn[nH]1
