Task: Answer the multiple choice question.
Query: Which compound has a 0.950\% 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) OCc1ccc(N=Nc2ccccc2)cc1
b) Cc1ccc(CCNC(=O)C2CCCN(S(=O)(=O)c3c(C)noc3/C=C/N(C)C)C2)cc1
c) COc1cc(CN2CCCN(C)CC2)cc([N+](=O)[O-])c1O
d) CCn1cc(C(=O)NCc2cccnc2)c(=O)c2cc(F)c(N3CCN(C(=O)c4ccco4)CC3)cc21
Answer: d. CCn1cc(C(=O)NCc2cccnc2)c(=O)c2cc(F)c(N3CCN(C(=O)c4ccco4)CC3)cc21
