Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 9.540\% 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 COc1ccc(OC)c(-c2nc(C(N)=O)c3[nH]c(=O)n(-c4ccc(F)cc4)c3n2)c1
b O=C(Nc1ccc(CN2CCOCC2)cc1)c1ccc(-c2cccc([N+](=O)[O-])c2)o1
c O=C(CN1CCCCC1)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
d CCOC(=O)c1cc(CC)sc1NC(=O)c1ccc(N2C(=O)CCC2=O)cc1
Answer: d. CCOC(=O)c1cc(CC)sc1NC(=O)c1ccc(N2C(=O)CCC2=O)cc1
