Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.638\% 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 other words.
Options:
a: CCCn1c(NC(=O)C2CCN(C(=O)c3ccc(F)cc3)CC2)nc2ccccc21
b: O=C(COc1coc(CN2CCc3ccccc3C2)cc1=O)Nc1ccc(F)cc1
c: Clc1n[nH]nc1-c1nn[nH][15n]1
d: Br.Cc1csc(Nc2cccc3ccccc23)n1
e: Cc1nc(Nc2cccc(O)c2)c2c3c(sc2n1)CCC3
Answer: c. Clc1n[nH]nc1-c1nn[nH][15n]1
