Task: Answer the multiple choice question.
Question: Which drug has a 2.509\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a COc1c(F)c(F)c(C(=O)Nc2c(C)cc(Br)cc2C)c(F)c1F
b CCCCNC(=O)C1(O)c2ccccc2NC(=O)N1c1ccc(Cl)cc1
c O=C(CNC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1)N/N=C/c1ccc(F)cc1
Answer: a. COc1c(F)c(F)c(C(=O)Nc2c(C)cc(Br)cc2C)c(F)c1F
