Task: Answer the multiple choice question.
Query: Which drug exhibits a -10.339\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) Cn1c(NCCCN2CCOCC2)nc2c1c(=O)n(Cc1ccc(Cl)c(Cl)c1)c(=O)n2C
b.) CCOc1ccc(NC(=O)Nc2ccc3c(c2)nc(C)n3C)cc1
c.) Cc1ccc[n+](CC2OCc3ccccc3CO2)c1.[Br-]
d.) Clc1ccc(-c2onc3c2CCCC3)cc1
e.) O=C(NC1CCCC1)c1ccc(CS(=O)Cc2ccccc2Cl)o1
Answer: a. Cn1c(NCCCN2CCOCC2)nc2c1c(=O)n(Cc1ccc(Cl)c(Cl)c1)c(=O)n2C
