Problem statement: Answer the multiple-choice question.
Query: Which drug has a -5.458% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(CN1CCN(c2ccccc2)CC1)Nc1ccc(-n2cnnn2)cc1
[b] O=C(O)c1cc2ccc3ccccc3c2oc1=O
[c] COc1ccc(C(CC(=O)c2ccccc2)S(=O)(=O)c2ccc(C)cc2)cc1
[d] COc1cc(/C=C/[N+](=O)[O-])ccc1O
Answer: d. COc1cc(/C=C/[N+](=O)[O-])ccc1O
