Task: Answer the multiple-choice question.
Query: Which drug has a 1.553\% 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) Oc1ccc(-c2nnc(Nc3ccccc3)c3ccccc23)cc1
b) Cc1ccc([N+](=O)[O-])c(OCCN2CCc3ccccc3C2)c1.O=C(O)C(=O)O
c) CCCOC(=O)c1ccc(-n2nnnc2SCC(=O)N2CCCCC2)cc1
d) C=CCN(CC=C)CCOc1ccccc1[N+](=O)[O-].O=C(O)C(=O)O
Answer: d. C=CCN(CC=C)CCOc1ccccc1[N+](=O)[O-].O=C(O)C(=O)O
