Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.262\% 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, d, or e without using any additional words.
Options:
a CCOCCCNc1nc(-c2ccccc2)nc2ccccc12.Cl
b CCOc1ccc(/C=C2\SC(=O)N(CCNC(=O)CN3C(=O)NC4(CCCC4)C3=O)C2=O)cc1OC
c NS(=O)(=O)c1ccc(CNC(=O)Cc2ccccc2[N+](=O)[O-])cc1
d N/C(=N\c1nc2c(c(=O)[nH]1)CCC2)Nc1ccccc1C(F)(F)F
e Cc1onc(-c2ccccc2)c1C(=O)OCc1nnc(-c2ccccc2)o1
Answer: a. CCOCCCNc1nc(-c2ccccc2)nc2ccccc12.Cl
