Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 9.885\% 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) CCNc1[nH]c(=O)n(C)c(=O)c1N=O
b) Cc1cc(=O)[nH]c2c1c(=O)[nH]n2C1CC(C)N(C)CC1C
c) O=C(NC1CCCCCC1)C1CCC(CNS(=O)(=O)c2ccc(Br)s2)CC1
d) Nc1ncc(Br)cc1S(=O)(=O)NCCC(=O)Nc1cccc(Cl)c1
Answer: a. CCNc1[nH]c(=O)n(C)c(=O)c1N=O
