Task: Answer the multiple choice question.
Query: Which compound exhibits a 16.445\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC1CCCN(c2ccc(C(=O)NCCc3ccccc3)cn2)C1
b: S=c1[nH]nc(-c2ccc3c(c2)OCO3)n1-c1ccccc1
c: O=C(NCc1ccc(Cl)cc1)C1CCC(=O)N(C2CCCCCC2)C1
d: CCS(=O)(=O)N1CCN(Cc2ccncc2)CC1.O=C(O)C(=O)O
Answer: d. CCS(=O)(=O)N1CCN(Cc2ccncc2)CC1.O=C(O)C(=O)O
