Task: Answer the multiple-choice question.
Question: Which compound has a 20.431\% 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 other words.
Options:
a: Clc1ccc2c(N3CCNCC3)ccnc2c1
b: CCN1CCN(C(C)C(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)CC1.O=C(O)C(=O)O
c: Nc1nnc(SCC(=O)Nc2cccc(S(N)(=O)=O)c2)s1
d: Cc1ccc(NC(=O)CCc2nc3ccccc3c(=O)[nH]2)cc1S(=O)(=O)N1CCOCC1
Answer: b. CCN1CCN(C(C)C(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)CC1.O=C(O)C(=O)O
