Task: Answer the multiple-choice question.
Query: Which compound exhibits a 7.624\% 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 additional words.
Options:
a: CN(CCCNC(=O)c1cn(C)c2ccc(S(=O)(=O)N(C)C)cc2c1=O)c1ccccc1
b: Cc1ncc([N+](=O)[O-])n1CCOC(=O)Nc1ccc(Cl)c(Cl)c1
c: O=C1CC(C(=O)O)(c2ccccc2)c2cccc(F)c21
d: CCOC(=O)C1=C(O)CSC1=Nc1ccccc1
Answer: d. CCOC(=O)C1=C(O)CSC1=Nc1ccccc1
