Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.099\% 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: NC(=O)C1=C[C@@H](c2ccc(Br)cc2)C[C@@H](OCCCCO)O1
b: CCOC(=O)c1c(NC(=O)C(c2ccccc2)c2ccccc2)sc2c1C1CCN2CC1.Cl
c: CCOC(=O)c1[nH]c2ccc(OC)cc2c1NC(=O)c1ccccc1C(=O)O
d: Cc1cc2cc(CN(Cc3ccc4c(c3)OCO4)C(=O)c3cnccn3)c3nnnn3c2cc1C
Answer: d. Cc1cc2cc(CN(Cc3ccc4c(c3)OCO4)C(=O)c3cnccn3)c3nnnn3c2cc1C
